Hello everybody,
i’m new to the world of Home automation and to this forum too but I did a lot of reading before 
I bought the following equipment that is just (less then 1 h our ago) arrived ;D
1 Vera Lite
3 Stellaz in 3 different rooms
1 SRT321 thermostat
1 SSR303 1 channel boiler actuator
My main goal is:
- Avoid “wife factor” and give THE POWER to the combination wife+thermostat so to override anytime/anycase all the conditions and let the house heated to sahara’s values in case of trouble.
- reach the thermal equilibrium (22 C) in all the rooms of my house when all the family is in;
- deactivate in the morning some rooms (kids and studio) since not in use stil mantaining 22 on the other rooms
4)Optional i would like to avoid to always have the boiler switched on and off by Vera every time one of the stellaz report a temperature lower then 22 but activate the boiler only when 2 or more stellaz report 21 or less.
I’m still wiring the actuator so i think only tomorrow i’ll have the system up and running but in the mean time i’d appreciate any suggestion to reach my purposes.
1)If i well understood the thermostat will in any case override any preset?
2)the Stellaz are already setted to the comfort zone that is 22C so i dont need any change.
3)Use a scene to insert the schedule for the boiler to stay on
4)Optional: Create a virtual switch that arm the boiler and using LUUP i should prepare a code that activate the boiler only if 2 of the stellaz are less then 21C. something like this?:
local lul_temp1 = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor1”,“CurrentTemperature”, 3) -Room Temperature from Stellaz1
local lul_temp2 = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor2”,“CurrentTemperature”, 4) -Room Temperature from Stellaz2
local lul_temp3 = luup.variable_get(“urn:upnp-org:serviceId:TemperatureSensor3”,“CurrentTemperature”, 5) -Room Temperature from Stellaz3
if (tonumber(lul_temp1) < 21 or tonumber(lul_temp2) < 21 or tonumber(lul_temp3) < 21) then
return true
end
Sorry for the long post
