I would like to use a wemos d1 mini to control a relay (power supply 5v). I have already programmed the wemos with Tasmota but I can not control the pin that must energize the relay. I have configured relay1 on D5 but when I press do not switch. Can you tell me how to do it?
Look at ESPEasy. It’s as easy as sending an MQTT payload.
MTA: Here’s a sample of setup using Wemos D1 Mini/D1 Mini Relay Shield and ESP Easy
Tasmota questions are probably better directed to the Tasmota github issues section.
