so finally coming back to you. I've tried a whole bunch of different things; shielded cable, separate power supplies, 4k7 resistor, etc. The only thing that worked was to shorten the cable. It's now about 30cm and not experiencing any issues any longer!
Thanks for the help!

Re: DHT22 signal drops when 12v fans are triggered
Thanks for the tip. I should probably also have mentioned the following: I can trigger all of the relays without any issues so long as I haven't switched on the 12v external power source. Only when I switch on the 12v power supply, which sends power to the fan, via one of the relays, do I stop getti...

(GPIO 2 and 4) - 4x float sensors, measure water levels in my water tanks (GPIO 5, 18, 19, 21) - 1x 4-way rela...

Hello All
Hi All
My name is Anton. I've been tinkering with ESP32's for a little while now.
I'm using one to monitor and control things within my greenhouse.
Keen to meet and chat to other like minded individuals.
Thanks
Anton
