Supla 16 X relay -- esp8266 + mcp23017

[bulek68]

Do I understand correctly that any relay can be set as GATE or TIMER?
If so, is it possible to add a gate opening sensor channel?

yes and yes

added 3 NO sensors

Gpio14(D5) -- Sensor NO

The system will work if I temporarily connect the 8x relay module?

Could you be more specific in your question?
you mean connect
ESP8266 + 2 x Mcp23017 + 8 x active high relay?

[bulek68]

I mean when I don't need a 16x relay but for example 8x or 12x.

Ok, I think I saw some of yours project in the forum.
while you have connected Esp8266 and the two Mcp23017
It doesn't matter how many channels you use (2-6-8-12), the others you leave disabled in the cloud,

You can also ask me for a specific number of channels.

Okay, you are right. My questions were theoretical.
Is there one or another possibility.
I'm sorry, I won't take your time anymore.

possibility of what?

and I have a lot of time to assist you.

In your project you used 4 modules with 4 relays.
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.
