OK, it's beginning to become clear. My initial gadgets & gizmos should arrive today, so I'll start tinkering, and I'm sure more clarity will come. Thanks for the quick responses, and for your patience. This is so far the best HA forum I've found anywhere!

@gohan said in Assistance on sensor project: While you are at it, get some extra parts too, just in case you fry something since in the beginning it is not that hard. And they're cheap.

Hi, sorry for the delay, I had just read your post and I could said "me too" But I solved the problem and it works for two years now. I explain my solution here, if the French don't afraid you. https://easydomoticz.com/forum/viewtopic.php?f=20&t=6497 I resume, a 7.5volts power supply, a passive injector, and a spécial home-made cable to bypass the RJ45 socket. The 7.5 v go to Vin-Gnd of the Nano to produce 5v wich is returned to the W5100. QED. Rpx.

@Olaf-Jacobs It's a straight analogue read on a single ADC pin relative to Vcc and ground of the Arduino Node. In my case it's a pro-mini, the ADC pin in this example earlier defined as "Pressure", the result radioed in only if the ADC reading has changed. Three other binary inputs for contactors are polled every second on separate digital pins (one of which is pin 3), which uses all 4 pins available on this pro-mini due to the radio etc. if ((!hidro&&!Hidro&&(counter2>=132))||initialise){ int incoming=analogRead(Pressure); if (prevolume!=incoming){ prevolume=incoming; sleep(50); float tankvolume=(((incoming-102.3)*6.704199635)+0.5);//5psi sensor send(msg8.set(tankvolume,0));//This is actual volume sleep(100); }} I'm not clear on the rest of what you're trying to incorporate or what pin 3 (digital interrupt) has to do with it, the pressure sensor signal goes to an analogue pin to enable the voltage to be read.

Use a latching relay. Here is one I found on Amazon. https://www.amazon.com/dp/B015MRQNXS/?coliid=I3LXTGKX4GEPUR&colid=31WWM91JAUE22&psc=1&ref_=lv_ov_lig_dp_it If you are trying to use with existing 3 ways use https://www.amazon.com/dp/B015MSYQ8Q/?coliid=I3RP8X9OMYWU97&colid=31WWM91JAUE22&psc=1&ref_=lv_ov_lig_dp_it Use an optocoupler to indicate lamp status...see the last diagram in this post. https://forum.arduino.cc/index.php?topic=435506.0
