Hi @neelam, welcome to the forum! The dimmer example should work. If you want to use only the esp8266 with wifi (no nrf/rfm or other radio), you'll also need to add gateway settings from https://www.mysensors.org/build/esp8266_gateway

@AWI I discovered it the hard way tonight. Lot of "Unknown sensor type" in my domoticz log. I have it working by declaring it as a distance, pressure etc. It's really dirty but at least for know I can track my RPMs. I guess I will try to poke around on the domoticz forums this week end to see if there is something cooking on their side. Thanks!

Nice job, efficient and clean ! I'm tempted to buy this microscope now, so I can make your led light

Not yet ! In fact, the interrupt must be short enough and fast enough to be sure to not miss the RFM69 interrupts. The code for 8 dimmers will not be really more complicated : in fact, each time we got a zero cross, we must set a timer to zero, and then wait the good amount of milliseconds to turn on the needed outputs. So, yes, we'll have an interrupts each 10ms (each time the wave crosses the zero, to be precise !), but I think all we have to do in the interrupt handler is set the timer to zero (or to micros() ...) and then on the main loop, wait the good amount of time for each output before setting them ON. Seems simple on paper, perhaps it will not work on the chip.... In facts, my main concern is : will the RFM interrupt be short enough to not disturb the zero crossing interrupt ? Although, not yet tested the RFM : do we NEED the interrupt pin ? Can't we poll frequently the RFM?
