The temperature should be reported work, if you have the probe. I have a few of these modules working as thermostats on some electric radiators. I also have a dimmer and a few shutter ones as well. They’ve been great and reliable to code against (no hacks or hoops to jump thru to get them to work).
You should also get the energy usage reports. I created this for my regular relay modules. So perhaps as they’re DC modules, they need some different code. If you have any logs or feedback, I can look into it and see if there’s a tweak to get the energy reports working for DC modules.
