Hello all,
I am looking to make some older devices (washing machine/ dryer) “Smart” i would like to activate the machine remotly based on the input of my solar panels. I am looking to put a switch over the start button of these machines.

Could you tell how you did it? Did you use the RE5V1C?

Willem,
i soldered the 4 cables to flash tasmota on it.
(photo from the internet)
i selected a useful profile ( i think Basic would do for the most of us.)
and added this to Homey with Sonoff app from @robertklep it works like a charm!

I am currently looking to upgrade this setup, i would like to have feedback on the Washing machine (running/ready) i figured out i could make a signal out from the door lock of the machine. And i am looking to use the same RE5V1C smart relay i have IO2 on there that i could use as an imput. but i am not sure if i can make this work with homey? currently have the RE5V1C running Tasmota and this is et up as basic device. Is there a way fir the tasmota software to broadcast the IO2 high / LOW and the Homey to receive this?
I know i could do this with ESP easy but this would mean i need to swap out the hardware i already have in the machine.
