@atermentis I noticed the sketch has the ”demo” DEADBEEFFEED mac address. Do all sketches have the same address?
All mac addresses on a ethernet network must be unique. If they are not unique, strange communication problems will occur.
I did not managed to get i working, shifted to a Raspberry PI, that works perfect - It seems that I also get version 1.x data from the gateway, Interesting if the gateway both can receive 1.x and 2.x data from sensors.
@nca78 Nope, you didn't misunderstand at all, my experience using Domoticz is limited to basics thus far... Will look into that..
Before this PV problem arose, had been looking at recording daily pump run times for both the domestic-supply and borehole pumps, easy enough for the borehole circuit, but the domestic runs LevControl->Contactor->PressureSwitch->Pump, so the auxiliary no-volts on the Contactor is permanently closed, hence a potential solution using a vibration sensor. Thinking about this overnight it may be possible to rewire LevControl->PressureSwitch->Contactor to solve the on/off indication from the auxilary on the main Contactor.
If the number of starts per 10 minutes/hour exceed a threshold , a separate alarm flag could be signalled by your suggested method.
