Thermostat Inhibit scene

Other Devices & Integrations Climate Control & Temperature Sensors
1

I’ve got a Horstmann C-stat 17-zw controlling my lounge, associated directly to 2 paddle switches for electric panel heaters. Vera can change the set point, but the stat looks after itself with it’s build in programme.
i also have a z-wave door sensor on the back door.

Is there a way to inhibit the panels from being on when the back door is open?
But once the door close, the stat set point is as it should be from it’s programme or vera’s setting (which could be anything)

(for example like the inhibit on the Smart Virtual Thermostat)

in Configuration Settings, Variable 3 is the max temperature setting available.
Could a scene drop this value somehow while the door is open, then putting it back up to 30 when closed. Hopefully the setpoint wouldn’t be affected by this at all.

Thanks.

You ask some good questions that I do not know the answer too …

Via the Associations … If you manually turn the paddle switches off with the Thermostat sense that and turn them back on ? Maybe it periodically turns them on while the thermostat calls for heat … do you know ?..
First you are going to need to understand the behavior of the thermostat.

If the Thermostat ONLY commands the paddle switches on when it first calls for heat … then you should be able to override from Vera after this with some logic (either LUA or Program Logic Event Generator) code.

As far as

Configuration Settings, Variable 3
I am not familiar with the device so I do not know if this is accessible via a scene.

If it’s not, you can still turn the paddle switches off until the door is closed. And maybe notify your Android or iPhone that the door is open yet the room is calling for heat.

I can still operate the paddles manually and via Vera.
It seems the thermostat sends a command every 15mins. I’ve put the thermostat so the heaters should be on, and turned the heaters off. It then turns them back in approx 15 mins later.

I guess in its simplest terms, if the door sensor is tripped, run a scene every 5 mins to manually turn the paddles off. Should work if not very smart??

You can use PLEG
Input Trigger
DoorOpen Door Sensor indicates it is Open
Heater1On Heater1 is On
Heater2On Heater2 is On

Input Device Property:
ModeState Thermostat ModeState Property

Conditions
TurnOff (Heater1On or Heater2On) and DoorOpen and (ModeState eq ‘Heating’)

Actions
TurnOff Turn of Heater1 and Heater2

Thank you. Will give it a try.
I still haven’t got my head round the PLEG thing. Couldn’t get a basic thing to work.

Now got it working though, through a PLEG event.
The thermostat doesn’t report heating mode though.

Thanks for the help.

How would I put a delay into the PLEG thing?

So if the door was only open for 30 seconds say, the heaters would be knocked out for a while.
Is there a way to only run if the door is tripped for 5mins?
Thanks.

I do not understand the two different scenarios.

But you can do:
TurnOff (Heater1On or Heater2On) and DoorOpen and (DoorOpen; Now > 2:00) and (ModeState eq ‘Heating’)

This will only turn off if the door is left open for 2 - 3 minutes. Now is only evaluated once per minute.

Richard!
Great idea!
Can you help me
I want to running one scene, when i setting (increment or decr. temperature) in the Virtual Thermostat? In the PLEG. plugin i can see in “Input” the Virtual Thermostat fields, but i dont know how can in this plugin, or other in lua code :flushed:
