You misunderstand. I use the relays only for things like reset
button, or boot mode jumpers, etc.

None of this. I always use the power supplies provided with the

So did I - using the web interface of the Tasmota firmware (which
you can also operate using curl, for example), but this is just
"open" in the network, zero security. That's why my goal is to go
for MQTT (and then probably Node Red).
