I have almost every light in my house ‘smart’. Whereas I can still use them manually (FTW = for the wife ).
There are three lights left, that I’ve postponed since they have 2-gang switches.
For my 1-gang lights, I use MOES Push Switches (these).
Of course they have 2-gang switches, but I want some help with the wiring/buying the right products.
So the aim here is to always have the back-up of manualy pressing the switch to turn on/off the lights, even if there is no connection with HA/Internet.
I soley use Zigbee in my setup.
These are the 3 lights I have left to smart-ify.
Attic light:
On the 2nd floor, this is the current wall switch:
Hall light
The right key of the wall switch in the last picture turns on/off the hall light.
Does anyone has sugguestions on how to get this nicely working? I was not able to make pictures of the wiring at the moment, but if they are a necessity I can provice them of course.
If I buy a 2-gang switch (ground floor) and put the Aqura t2 relay at the 1st floor, how does it operate? Do I need to tie everything together software wise? How will I be guarenteed it still works ‘offline’ ?
A relay and a smart switch are the exact same thing the only difference is that a relay does not come attached to a physical switch.
the t2 and shelly relay’s are local only relays, you are just putting them between your physical switch and the outputs they already control to make them smart.
If you already have a 2 gang smart switch that will fit in the places that you want to swap with then ignore the relay as again its for spots where you can’t install a smart switch as a replacement to get your setup you are looking for.
Since I have room to replace two of the switches, it would be easier to buy them.
I’ve watched the video and it was very helpfull. A single Gang is so easy by just replacing the switch. I feel a bit uncomfortable since it is a new thing for me (2-Gang).
I don’t need to use a relay at both switches, just at one point. Right?
You need to make sure that the smart switch you pick has the option for a common wire that is shared with the socket switch you want to connect I would say, I would get an electrician out just to validate what wires are for where and what is the best smart switch to use for your setup needs for this situation.
Else I would remove the power socket switch from the common side of the main switch and just put in a relay directly in the socket switch to control it directly separate of the main switch that will only handle the lights.
The general idea with the setup is to have the 3rd switch act as a toggle so that it’s always opposite to what the main switch is set hence the common if using a direct smart switch/relay setup that has the option which the t2 does (at the bottom it has SW1, SW2 and COM) you can wire in the 3rd switch to the com port on it and set it up in the settings to control them this way without replacing your current switches fully.
