Hallo Kees,

Yes i found it thank you verry much!!!!.
where did you attach for example Burner on/off to because if i attach it to an switch i can control it and i want to read.
or does it turn the switch in the dashboard on if burger gets enabled?

kind regards patrick

Yes use a switch sensor.
The switch in the dashboard does nothing if you toggle it by hand. It only reflects the state of the 'burger' as you called it. :-)

Hallo Kees

the switches are working i tested it trough enabling my heating but at the domoticz idx numbers you have IDXhotwater and IDXboiler but i dont get value at both of them not as switch and not as tempratuur.

Yes it seems I forgot to add the code fragment for the IDXboiler HTTP request.

IDXhotwater is in there, but it will only send the value if it has changed.
If you turn on the hot water for only a short moment, it can miss the change in value, so turn it on for longer and it should send the change to Domoticz.
