@skywatch @sindrome73 This is what I do, too. Note that it is wait(), which is a MySensors function and not delay(), an Arduino function. wait() checks for MySensors messages, delay() halts all process, thus a message might be missed.

@OldSurferDude If you have a pi2 or pi4 you could try with that instead of the pi3. Pi3 was known for being a bit 'different' with some applications. A quick and simple test if you can.

Thanks @OldSurferDude. I am bit newbie in circuit design, does the R20 inrush current limiting resistor must be 2W? or the 0.5W resistor in the BOM works fine?

Hello, thank you very much for your quick help. I think I'll be able to move forward with #define MY_PASSIVE_NODE. Am I understanding this correctly? If data still arrives at the gateway, is that OK? What are the disadvantages of this function? I tried it out. It seems to work. Best regards, branther

@mfalkvidd This statement is the crux "It just needs to expose its capabilities in a form the AI can use". The IoT device would have to present its capabilities in MCP-ese. This could be complex, for example, one could tell the AI, "Heat my house in a way minimizes on/off cycles." It would have to know a large number of things, temperature (indoor, outdoor, outdoor and indoor heat transfer fluid), fluid flow rate, fluid pressure, indoor and outdoor fan speed, how to regulate those speeds, and more. What I think I'm trying to say is that it will create more overhead. And this AI, where does that reside? If not in the cloud (the cloud has its own set of negatives), then on a home server? ... yet more overhead. It seems like instead of simplifying our lives, it would overly complicate them. Of course, I guess, we could ask AI to design our IoT devices :o -OSD

Added some 3d sketches so you can see what I'm trying to accomplish. Unless ofc someone will tell me this is a bad idea
