Looking for a zigbee switch/relay that can still be controlled on a mechanical way (impuls)

Not sure if it exists, but I am looking for a DIN zigbee switch / relay that can also be controlled by an oldskool impuls wall button 12/12V.

The reason for this is that I want my lighting to work/controllable in all situations:

  • when Home assistant is down
  • when my wifi/internet is out, I know zigbee can operate without wifi but better safe then sorry
  • because I want the wires to be there in the walls/floors as some kind of a last resort/backup in case at some day I would need them
  • if I sell my home and the new owner doesn’t like a smart home :wink:

So, I am actually looking for something like the link below but then also controllable by an impuls button 12/24v switching between ON and OFF

Zigbee Smart Circuit Breaker 1P 63A Din Rail

Maybe I found something that could fit my question in the meantime:

Earu Zigbee Relais

But it can be controlled by one or more tact(icle) switches. I am not sure but a tactile switch is nothing more then a closed circuit without any current on it. In other words it is just connecting A1 with A2 via a pulse button. Correct?

Any other good alternatives?

Not an actual switch, but touch control and they work fine stand alone :wink:

They have a whole range of them, switches, dimmers, curtains, etc with or without neutal

But most important fact is that they are wife-approved :rofl:

Haha… I removed the wife-approved part in the original topic, but you must have seen that part and/or you and I think like-wise :slight_smile: but indeed that also plays an important role in not-so-tech people adopting SMART homes and features.

I know that it is fact not only a relay switch, but the touch control is for switching the main power of the circuit on/off, so in my opinion the core functionality is being a (power) circuitbreaker either by touch, timer/scheduled, or automated.

The questions remaining:

  • Can it be controlled by having a closed circuit between A1 and A2 by the means of an external touch button (wall impuls switch) instead of tact(ile) switch like the diagrams are showing?
  • And is this version already supported by the z2m project, I don’t think so (yet)

The link that you mentioned to that vendor’s wall switches is actually doing something similar, but by having all the cables (both power and signal) running to your central power box your are (I think) more in control and more flexible in changing something in a central location.

Or do I miss something taking the new/smart technologies/hardware in mind. Is my way of thinking ‘oldskool’?

This range also has a version that requires a neutral cable, and I hear a real ‘click’, so it does use a relay…
I only think it has only one output (so the phase live wire is internally wired)

They also have a ‘no neutral’ version, which uses the internal resistance of the bulb, they work fine, but could be an issue with certain low power LED’s (haven’t had the issue myself (yet)).

Placing it central; it requires a lot of extra cabling, so why bother :thinking:
For me it is easier to just replace the existing switches :wink:
(although for some of my dimmers I needed to pull an extra neutral cable, as it was not available at the switch)
And the dimmers are a ‘wife’ requirement; she get confused with dimmers using just one momentary switch (single click is on/off, pushing long is dimming), so she insisted having 3 buttons :smiley:

ok, I understand that… but for my home everything was already setup/installed and controlled from the power box. So indeed much more cables…

Now I am at the stage to extend my power installation… so I want to keep it similar to the rest of my house, driven from the power box but this time hopefully also smart :wink:

if you drop the 12/24 impuls button, and just use a no voltage impuls button, these

work with Zigbee2MQTT and one or more impuls buttons/

That is the whole thing… I know everything can be solved by a non voltage zigbee switch, but then it doesn’t work anymore in case of a HA or zigbee issue. I want to achieve that things continue to work in all scenarios unless there is a power outage or something.

These work even if Zigbee is down. Just like a normal non-smart relay / contactor. I replaced these
Server Busy with the mentioned Zigbee ones.

Funny… I was looking back at the link you shared and when looking at it again it seems exactly the same relay switch that I shared in the 2nd comment on this topic except maybe the brand.

So, you used these switches in your home … right? And it requires a no voltage impuls button?
So… am I right that it simply requires a connection between A1 and A2?

If so, then this also requires a signal wires to my wall switch, but there wouldn’t be any voltage on it them… but it keeps te option open to an old skook wiring with voltage circuitbreakers.

@francisp Can you confirm my view on this?

Indeed, that is how I connected them.
