GPIO Output as switch entity in home assistant #252

Closed bjornmorsman closed 1 day ago

bjornmorsman commented 1 month ago

Hello,

is it possible to have a relay that is configured as a gpio output in the nodemcu not activated by a bit of the boiler but by a switch entity from home assitant?

I have a boiler with 2 zones, zone 1 is controlled by an opentherm thermostat and zone 2 by an on/off thermostat.

I would like to control this 2nd zone with a relay via the nodemcu

thank you

Hi @bjornmorsman

You can switch relays as much as you like based on any information. The easiest way to do that is to use automation options in home assistant to control a relay seperate from the OTGW. Just use the binary readout output to control a relay you need.

Hope this solves your issue, Robert
