I want to add more relays to the Cerbo GX to control external devices. Which solution could work for me (and the Cerbo GX / Node-RED flow)?
Easy ones for AC are Shelley relays. You can use sonoff ones as well.
Shelley sounds great, are these easy to integrate into Cerbo GX?
@Marc Fritschi some Shelley's are easier than others
I have the Shelley Pro 4PM, I use it more for monitoring
the electric fire is on switch 0
the tumble dryer on switch 1
my cascading MP 48/1600 invertor on switch 2
the lower socket (garage heater) on switch 3
and the flow looks like this
and my Gui looks like this
the best part is that I can automatically switch the Fire, switch 0, off and on again, to stop mother turning it up after the sun has gone down :)
the lower socket (garage heater) on switch 3 goes on and off based on air temp from a RuuviTag next to my batteries
and that looks like this
I believe some of the Shelleys can also switch DC loads... but I have never done that.
hope this helps you
@Marc Fritschi
how familiar are you with node red ?
if you need more, once you have your Shelley installed and ready to go
give me a shout, I am happy to help
