Updating Setpoint device and script - logic is failing me

[rjblake]

I have a added a Setpoint device (tadosetpoint) and can use this to override my heating if the needs arises. If I change its value (e.g. current heating program is 18deg to 21deg), it runs a script (using LUA devicechanged[tadosetpoint]). Reason I'm calling a PHP script is that I already have coded functions for the Tado and don't have the LUA knowledge to simply change them. Guess I could if needed, but the logic in the problem would still remain.

The LUA/PHP part is works fine by itself. However, I also want to be able to get the setpoint value on a regular basis from the thermostat (separate script that pulls information from Tado every minute and updates devices if they've changed, but if I update the device it'll trigger running of the script again and likely end up in a never ending loop. Any suggestions?

Code as it stands:

Code: Select all

local tadosetpoint = 'Tado Setpoint'
commandArray = {}
 
if devicechanged[tadosetpoint] then
    tadosetpoint_temp = tonumber(otherdevices_svalues[tadosetpoint])
    if tadosetpoint_temp > 25 then
        print('Tado Setpoint too HIGH - Out of permissible range')
    elseif tadosetpoint_temp < 6 then
        print('Tado Setpoint too LOW - Out of permissible range')
    else 
        os.execute('php70 -f /volume1/web/heating/tado.php '..tadosetpoint_temp)
        print('Tado Setpoint Change to: '..tadosetpoint_temp)
    end
end
 
return commandArray
