It gives me these MQTT messages that I dissect later in node-red: tele/geiger/RESULT {"SSerialReceived":"CPS, 0, CPM, 20, uSv/hr, 0.11, SLOW\r\n"}
Hi, I would also be interested in the solution with the DIY Geiger counter. The MightyOhm Geiger is too expensive for me. Are there other DIYs with a serial port for Tastmota? Can you please tell me which DIY you used. Thank you very much
I simply connected power and serial of the MightyOhm kit to a Wemos D1 mini, and that was it. I guess pretty much any Geiger counter will do, be it pulse or serial based. I'd consult my preferred search engine.
