Hi,

I am looking for a google home/assistant supported DIY non potential relay delivered from china.

It is easy to find a google home supported smart switch with 250v output like this

But I simply need it without the output and with only a non potential relay switch.

What do I search for to find this?

Happy new year

 

What is a non potential relay?

 

non potential relay

I think it is a relay not connected to the power line. Like a "Sonoff relay board".

 

What do I search for to find this?

If I understand you correctly regarding a 'non potential relay', try searching for "volts free contacts".

 

Volts free, yes

I guess no one manufactures what I am searching for as no one knows of any. I thought it was just me who didnt know what to search for.

I might go with this solution then: https://www.chatteris.biz/blog/sonoff-basic-voltage-free-relay-changeover-modification/

 

I thought Sonoff had a relay board with unconnected relays (4) but I could not find it. I thought about cutting traces.
OR adding a 220vac relay coil to the output of a "basic" Sonoff thing.
I add a sell phone charger to the output of the Basic Sonoff. Now I have 5 volts that is there or not there to turn on/off some small things.
