This looks awsome and exactly what i was after. I use ESP8266's with NRF24L01+'s as relay nodes connecting back to a cloud mqtt server but have had to statically assign id's.

Thanks!!!

Also keen to run this on an ESP8266 would be a great for bridging.

@BulldogLowell I have powered it off an external battery pack. Same story!

its worth a try, however this works 100% fine when there is not a fan connected I might try a different AC device to see if that is just as reliable as no AC device connected.

@BulldogLowell im using one of these onto the 5v pin of the board:

I have also tried feeding it via USB of a 2.1 amp supply with the same results.

I have D3 signal low to trigger the relay. The same 5V source powers the relay, but this works fine if no load is connected.

Hi,

I have a sensor node driving a fan and sometimes when toggling the relay the node locks up. I am using a nano board and when it locks up the TX led stays solid.

The relay board is opto isolated. I have done some research about the interference that can be caused by a relay switching a motor, but I don't understand the solutions and given its 240v I don't want to make changes to the 240 side unless I fully understand them.

I have tried swapping out the radio, the nano and the relay.

I have not been able to reproduce the fault when the fan is disconnected.

My skills are quite basic so any simple advice would be very much appreciated!

Got it working first try! Can see data coming back from my Temp and Hum sensors!

Looks like a great tool.

Thank you!
