Nest thermostat

Hallo Lua world,
Does someone have some more information to manipulate a Nest thermostat v3?
I'm using the presence detection to set the Nest on "Away" by using:
local nest_away = 'Home Living Room Away'
commandArray[nest_away]='On'
This works,
Then I change the Setpoint by:
commandArray['UpdateDevice']='509|15|15'
where 509 = IDX for my Nest Thermostat
first 15 not a clou, (nvalue)
second 15 = setpoint temperature (svalue)
Although I have an error message "Lua is running more than 10 seconds" it works, I know why I have this error message.
The problem is I should set the ECO mode of the thermostat, cause after changing the Setpoint, the scheduler from the thermostat is overriding my setpoint.
So can someone help me out here?
I know, there's an away function in the Nest itself but that is not waterproof, I'm using the Pilot app to detect the presence of my phones and thats 100% accurate, while the Nest app detects 5 out 10!

Any luck fixing the problem? my setpoint command runs also for more then 10 seconds but it works..
Code: Select all
if (devicechanged['test']=='On') then
commandArray['UpdateDevice'] = '368|0|21'
end
i also have no idea what to fill in at the nValue so i guess it should be '0' ?
i found another way to set it using an json command:
Code: Select all
if (devicechanged['test']=='On') then
commandArray["OpenURL"]="http://127.0.0.1:8080/json.htm?type=command¶m=udevice&idx=368&nvalue=0&svalue=21"
elseif (devicechanged['test']=='Off')then
commandArray["OpenURL"]="http://127.0.0.1:8080/json.htm?type=command¶m=udevice&idx=368&nvalue=0&svalue=18"
end

I use "SetSetpoint" to set the setpoint on my Nest v3.
Works like acharm and don't have those "Longer then 10 seconds" error
commandArray['SetSetPoint:MySetPointIdx']='20.5'

I tried that, but nothing happens (Nest v3)

I assume that you set the correct idx as seen under settings->devices and not under hardware

Strange then, which Domoticz version are you running at the moment?
As for me i'm on the latest beta version.
I don't know in which version this "SetSetPoint" was introduced.

I'm on v3.7320
You are using in your Nest script:
Code: Select all
commandArray["OpenURL"]="http://"..domoticz.ip..":"..domoticz.port.."/json.htm?type=command¶m=udevice&idx="..nest_setpoint_idx.."&nvalue=0&svalue="..setpoint_high..""
Or have you not updated your pastebin?
-edit-
Maybe it doesnt work in current beta?

Fixed it, tostring was missing, the following code works
Code: Select all
local nest_setpoint_idx = 368
local setpoint_low = 17
local setpoint_high = 21
commandArray = {}
if (devicechanged['test']=='On') then
commandArray['SetSetPoint:'..nest_setpoint_idx]=tostring(setpoint_high)
elseif (devicechanged['test']=='Off')then
commandArray['SetSetPoint:'..nest_setpoint_idx]=tostring(setpoint_low)
end
return commandArray
thanks Siewert, i think i going to 'borrow' your script

Yep... On a second thought i forgot to mention that.
Go ahead and use everything you want, but be aware some snippets use a function called from the functions.lua
