I've got a HC2, Nest and some Danfoss-valves, eventually I want a Multi-zoned Heating Systems.
= Modulating through a Nest =
Problem is I live in The Netherlands and out here usually have Modulating Central Heating Systems. So I can't just use The Heating Panel and keep my pipes heated or not according to the outside temperature.
With the Modulating system, I need to control my Central Heating through for example a Nest. I am controlling the Nest through an API, with the help of @TW1979 in topic "https://forum.fibaro.com/index.php?/topic/22466-nest-thermostat-v3-fibaro-plugin-not-updating-workaround-found"
= LUA =
I've read up on the Danfoss-radiator valves. (special thanks to: @tinman@Momos@hTiger1@petergebruers) * They're not that reliable. So before I start with the Multi-zone-LUA, here is my description of the LUA I'm gonna write for the one-room-system.
Can someone tell me if this is gonna work?
Global Variables:
int Target_Temp_room1
Function:SCHEDULE
Trigger : Time
Action : Changes Target_Temp_room1
Function:EDIT Target_Temp_room1 WHEN THERMOSTAT IS CHANGED MANUALLY
Trigger : Physical changes at Thermostat or manual changes in Fibaro GUI.
Action : Change the Target_Temp_room1 accordingly
Function:TURN ON CENTRAL HEATING (by turning on the Nest)
Trigger : Target_Temp_room1 is changed
PreExec : Check if I am home (if I'm Away do nothing)
Action : check how much the Target_Temp_room1 is away from the
FIBMOTION:current_temp_room1 (=Temp_Difference_room1) --> Set API:Nest_target
to API:Nest_Current_Temp + Temp_Difference. Set the Thermostat to Target_Temp_room1 if it isn't already.
Function:TURN OFF CENTRAL HEATING
Trigger : Room Temperature has reached the Target_Temp
Action : Set API:Nest_target to API:Nest_Current_Temp
