Thanks, that is clear. I have a relais with both NO and NC, similar to this one: https://www.otronic.nl/nl/5v-hoog-vermogen-relais-250v-30a.html, and currently using the NO (because the relais says NO can handle higher currents than NC). I now switch both the VDD and trigger wire, and that works ...

Hi, I have the following case: I have an external thermostat to control a fridge, with an on-board relais. Because this on-board relais is not very powerful, I use this first relais to toggle a second relais (30A) to power the fridge. Now, in addition to switching the on/off pin of the second relais ...

Hi there, Maybe a stupid question, but how to wrap text in a button set selector switch, so that my buttons fit in the box?

Hi Jan, I don't know the solution, but the error message says that it fails performing a numeric calculation because the format of the numbers is not the same ("attempt to perform arithmetic on a table value (field 'previousData')"). That means the error is in the script line: local verschil ...

Hi there, I'm trying for a long time to control the room temperature setpoints via dzVents, for example to change the setpoint temperature when a switch is activated. I have an iSense thermostat and an Opentherm Gateway. This works fine for retrieving the OTGW data in Domoticz, and it also works to ...

Thanks for the great tips in this thread. I'm trying to do the same, but I don't get it working yet. When typing in my Chromium browser (at the RPi that runs Domoticz): http://127.0.0.1:8080/json.htm?type=command&param=sendopenthermcommand&idx=39&cmnd=TC=20 it gives me the response { "status" : "ERR ...
