My opentherm is working fine upon one item:
OpenTherm Gateway 00000007 General Pressure 18.0 Bar

It is actually 1.8 bar...

Can anybody give me a pointer how to get this correctly displayed as 1.8 bar?

I already have mysensors temp and pH probes in my aquariums. Would he very interested on NH4 and NO3. Do appropriate probes and sensors exist that can be hooked to an Arduino (at a reasonable price of course) ? Can confirm mysensors + arduino zero works good. Had only a groundloop problem with pH ...

This sensor, LJ18A3-8-Z/BX 8mm, detects the printed circuit when passing by. I made the same construction with a hose clamp and iron holder. Working fine on 12V. It is rather large, but no downside so far; https://nl.aliexpress.com/item/LJ18A3-8-Z-BX-8mm-Approach-Sensor-Inductive-Proximity-NPN-NO ...

I was also searching for this; Now using name for my scripts, instead of IDX.

You can just use: otherdevices_idx["Bathroom Light"]
