Thats why I logged on ... but got distracted by the other crap again.
Anyway ... a while back I had an issue with a dimmer switching off every time I switched of a relay ... I had an idea of what I thought it might be ... but then this morning when I got up a 3 am to learn more about node red and MQTT something interesting popped up.
Someone mentioned using a a diode to reduce the voltage spike when the rely switches off ... during discussion with other people a capacitor was mentioned ... which I tried but it didnt help ... what did help was when I connected more lights ... almost like the resistance went high enough for the voltage surge to dissipate into the circuit.
Any comments ... a diode or capacitor?
I also saw a circuit with a diode in line/series with a coil ... I will have to do more research into why you would do that.
