Getting data from a sensor in a file

[Cor]

Time to adjust something here

Writing these temperatures in a file works very well.
Unfortunately, with the blue iris programm you can only have 9 macro’s 9 in my case 9 different temperature overlays.

I use this code now that every temperature sensor will have his own .txt file

[code]local devID = 128
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/oatemp.txt”, “w”)
file:write(temperature … “\176C”)
file:close()

local devID = 43
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/bathroomtemp_up.txt”, “w”)
file:write(temperature … “\176C”)
file:close()

local devID = 48
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/bathroom_main.txt”, “w”)
file:write(temperature … “\176C”)
file:close()

local devID = 189
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/Vorlauf.txt”, “w”)
file:write(temperature … “\176C”)
file:close()

local devID = 186
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/Heizung.txt”, “w”)
file:write(temperature … “\176C”)
file:close()[/code]

Is it possible to write all these variables in 1 files, and in a specific order, (below each other) ,like:

19,9 ?C
21 ?C
60 ?C

etc.

many thanks,
Cor

Is it possible to write all these variables in 1 files, and in a specific order, (below each other) ,like:

19,9 ?C
21 ?C
60 ?C

Yes that is easy to do:

[code]local devID = 128
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/oatemp.txt”, “w”)
file:write(temperature … “\176C”)

devID = 43
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write(temperature … “\176C”)

devID = 48
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write(temperature … “\176C”)

devID = 189
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write(temperature … “\176C”)

devID = 186
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write(temperature … “\176C”)
file:close()[/code]

[Cor]

NICE!!! ;D

To makr it near perfect , After every variable there is now this " “\176C” code to make it de Celcius character. Is it possible to have before a variable the name of the variable than the variable , than the Celcius sign?

Like this:

Bathroom xx.x ?C

Thanks,
Cor

[RexBeckett]

No problem. Just adjust the text in the following:

[code]local devID = 128
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/oatemp.txt”, “w”)
file:write("Outside " … temperature … “\176C”)

devID = 43
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Bath Main " … temperature … “\176C”)

devID = 48
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Bath Up " … temperature … “\176C”)

devID = 189
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Vorlauf " … temperature … “\176C”)

devID = 186
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Heizung " … temperature … “\176C”)
file:close()[/code]

Hi RexBecket,

I just changed the LUUP code , but there is somewhere something wrong , the variables are not written below each other on the next line , but next to each other.

Like this:

Ambient 20?CBuffer 43?CBoiler 40?CWater 34?CBathroom Upstairs 12?CBathroom Downstairs 14?C

This is the LUUP code:

[code]local devID = 186
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/heating.txt”, “w”)
file:write("Ambient " … temperature … “\176C”)

devID = 187
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Buffer " … temperature … “\176C”)

devID = 188
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Boiler " … temperature … “\176C”)

devID = 189
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Water " … temperature … “\176C”)

devID = 43
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Bathroom Upstairs " … temperature … “\176C”)

devID = 48
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Bathroom Downstairs " … temperature … “\176C”)
file:close()[/code]

Is it possible to have it written on seperate lines?

Like this?

Ambient 20?C Buffer 43?C Boiler 40?C Water 34?C Bathroom Upstairs 12?C Bathroom Downstairs 14?C

Many thanks,
Cor

[RexBeckett]

Is it possible to have it written on seperate lines?

Sure. Just add a newline character (\n) at the end of each output string. So replace “\176C” with “\176C\n” in each file:write(…) statement.

[Cor]

Cool ;D,

It’s working perfect, many thanks!

[Cor]

A little update,

I would also like to add the humidity. I tried to add this in the LUUP code , but it didn’t work.

[code]local devID = 37
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/Living_room.txt”, “w”)
file:write(temperature … “\176C”)
file:close()

local devID = 40
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/corridor.txt”, “w”)
file:write(temperature … “\176C”)
file:close()

local devID = 91
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/heating.txt”, “w”)
file:write("Ambient: " … temperature … “\176C\n”)

devID = 92
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Buffer: " … temperature … “\176C\n”)

devID = 93
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Boiler: " … temperature … “\176C\n”)

devID = 87
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Bathroom Upstairs: " … temperature … “\176C\n”)

devID = 78
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Bathroom Downstairs: " … temperature … “\176C”)

devID = 79
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentHumidity”,devID)
file:write("Bathroom Downstairs: " … humidity … “\176C”)

file:close()[/code]

It is the bottom one which I would like to include with device # 79

Anyone sees what I am doing wrong?

[akbooer]

This is certainly wrong…

devID = 79
temperature = luup.variable_get("urn:upnp-org:serviceId:TemperatureSensor1","CurrentHumidity",devID)
file:write("Bathroom Downstairs: " .. humidity .. "\176C")

You would need instead…

devID = 79
humidity = luup.variable_get("urn:micasaverde-com:serviceId:HumiditySensor1","CurrentLevel",devID)
file:write("Bathroom Downstairs: " .. humidity .. "\176C")

…or something along those lines.

I haven’t checked the whole thing, there may be others.

You need to understand where the serviceIds and variable names come from. This would be a start: http://wiki.micasaverde.com/index.php/Luup_UPnP_Variables_and_Actions

[Cor]

Super!

Thanks, It works now.

Understanding all the coding :o … but it makes more sense now.

Cor

[sre]

Thanks @RexBeckett. I was looking for this info for some time. Can you also tell me how to fetch the time stamp along with the temperature info please ?

[akbooer]

@sre

Can you also tell me how to fetch the time stamp along with the temperature info please ?

The documentation here:

http://wiki.micasaverde.com/index.php/Luup_Lua_extensions#function:_variable_get

Would tell you that all you need is:

devID = 79
humidity, tstamp = luup.variable_get("urn:micasaverde-com:serviceId:HumiditySensor1","CurrentLevel",devID)

However, this may not be reliable if the system has reloaded in the meantime.

[sre]

Thanks @akbooer. It was really valuable information

Hello again ,

All was working very well … untill I updated the firmware this morning … :-
I got it partially working again , but wierdly enough 2 files are not working.

This is the complete Luup code which was working with the previous firmware:

[code]local devID = 37
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/Living_room.txt”, “w”)
file:write(temperature … “\176C”)
file:close()

local devID = 40
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/corridor.txt”, “w”)
file:write(temperature … “\176C”)
file:close()

local devID = 117
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/garage.txt”, “w”)
file:write(temperature … “\176C”)
file:close()

local devID =212
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/OAT.txt”, “w”)
file:write(temperature … “\176C”)
file:close()

local devID = 212
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/heating2.txt”, “w”)
file:write("Outside: " … temperature … “\176C\n”)

devID = 40
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Corridor: " … temperature … “\176C\n”)

devID = 37
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Living: " … temperature … “\176C\n”)

devID = 117
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Garage: " … temperature … “\176C\n”)

devID = 228
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Hobby: " … temperature … “\176C\n”)

devID = 230
humidity = luup.variable_get(“urn:micasaverde-com:serviceId:HumiditySensor1”,“CurrentLevel”,devID)
file:write("Hobby: " … humidity … “%”)
file:close()

local devID = 91
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/heating.txt”, “w”)
file:write("Ambient: " … temperature … “\176C\n”)

devID = 92
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Buffer: " … temperature … “\176C\n”)

devID = 93
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Boiler: " … temperature … “\176C\n”)

devID = 94
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Radiator: " … temperature … “\176C\n”)

devID = 87
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Bathroom Upstairs: " … temperature … “\176C\n”)

devID = 88
humidity = luup.variable_get(“urn:micasaverde-com:serviceId:HumiditySensor1”,“CurrentLevel”,devID)
file:write("Bathroom Upstairs: " … humidity … “%\n”)

devID = 78
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Bathroom Downstairs: " … temperature … “\176C\n”)

devID = 79
humidity = luup.variable_get(“urn:micasaverde-com:serviceId:HumiditySensor1”,“CurrentLevel”,devID)
file:write("Bathroom Downstairs: " … humidity … “%”)
file:close()

local devID = 228
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/Hobby.txt”, “w”)
file:write("Hobby: " … temperature … “\176C\n”)

devID = 230
humidity = luup.variable_get(“urn:micasaverde-com:serviceId:HumiditySensor1”,“CurrentLevel”,devID)
file:write("Humid: " … humidity … “%”)
file:close()[/code]

Now , 2 files will not create , this part which is at the bottom:

[code]local devID = 228
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/Hobby.txt”, “w”)
file:write("Hobby: " … temperature … “\176C\n”)

devID = 230
humidity = luup.variable_get(“urn:micasaverde-com:serviceId:HumiditySensor1”,“CurrentLevel”,devID)
file:write("Humid: " … humidity … “%”)
file:close()[/code]

And this part in the middle, here the file is created , but the file remains empty:

[code]local devID = 91
local temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
local file = io.open(“/www/blueiris/heating.txt”, “w”)
file:write("Ambient: " … temperature … “\176C\n”)

devID = 92
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Buffer: " … temperature … “\176C\n”)

devID = 93
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Boiler: " … temperature … “\176C\n”)

devID = 94
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Radiator: " … temperature … “\176C\n”)

devID = 87
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Bathroom Upstairs: " … temperature … “\176C\n”)

devID = 88
humidity = luup.variable_get(“urn:micasaverde-com:serviceId:HumiditySensor1”,“CurrentLevel”,devID)
file:write("Bathroom Upstairs: " … humidity … “%\n”)

devID = 78
temperature = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”,devID)
file:write("Bathroom Downstairs: " … temperature … “\176C\n”)

devID = 79
humidity = luup.variable_get(“urn:micasaverde-com:serviceId:HumiditySensor1”,“CurrentLevel”,devID)
file:write("Bathroom Downstairs: " … humidity … “%”)
file:close()
[/code]

The device ID are still correct …
anyone has an idea why it does not want to write , the rest of the LUUP code , writing it’s files works fine.

Thanks,
Cor

[akbooer]

…so what errors are shown in the log?

[Cor]

I downloaded the LUAupnp.log file ( That is the one you are referring to?)

I might have found the problem , But I have no idea what to do with this info:

It says It can not find a device type… Very wierd since before the firmware update this morning it was working fine.

Thanks,
Cor

[akbooer]

I’d hazard a guess that it’s having a problem with device #91… are you sure it’s there?

[Cor]

I think you found my problem ;D !!

The device is indeed gone! :o , It is a universal sensor with 5 temperature sensors, the names are gone , the id changed …crap!!!

Anyway , I now know what to do tonight! >:(

Many thanks,
Cor

[Cor]

Since a couple of days , it doesn’t work anymore.

I updated to the latest firmware , since than the folder www\blueiris was removed.
I created in winscp the folder again , and it seemed to be working. but it is not. it did work once or twice , but now nothing anymore , when I start the scene manualy , nothing is written to the files.

Anyone has an idea , maybe something wrong with the rights of the folder?

Attached a screenshot of winscp , below the Lua code from the scene . ( Lua code was not changed).

I think I found it …

Due to the firmware update a device was gone , after getting it back , it had a new device ID . After changing the Lua script with the correct device ID , it seems to be working again.

Cor

note to myself: Only do a firmware update on the first day of vacation to iron out all the errors in the following days.
