I know that in cloud I can run 2,4,8,16 channels.
I asked if I would physically connect 2 modules with 4 relays then this construction would still work.
Of course yes

The GPIO have not been used yet. :twisted: :twisted: :twisted:
I think that many people will be missing up to 8xDS and DHT22 / BME280.

Is this possible? :D Is it just a matter of time :P

Looking at what you can force these ESP devices to do, I would not be surprised that one day it will happen.

Me again. :twisted:
Could you suggest how to secure sensor inputs for long cables (about 30m).

EDIT:

Maybe this- EVERLIGHT EL817 will be ok?

or you can use DirectLink.

I noticed a certain pattern.
When the relays are turned on and the module loses power and returns again then the relays are turned off and the application indicates their switching on.
