Domoticz

Hi,

When I started with Domoticz about 4 years ago I used Aqara Door & Window sensors to make my existing wall switches smart. With some coding in dzVents I have programmed actions with 1, 2, 3 and 4 pulses, see my post here. Although these switches still work well, the main reason for creating them was the unavailability of battery powered switch modules that fit behind an existing wall switch. I recently checked the Zigbee device database but did not find any useful alternatives to my solution again. Any suggestions?

Peter

Are you looking for something like this?

You can put labels on them if you want, and they can be placed anywhere

Together with controlling Philips Hue, or a shelly or a zigbee dimmer it's a great combo

Hi Gizmocuz,

No, I'm looking for a module that fits behind the wall switch so the wall switch still looks the same as before it went smart.

You can use something like this: https://amzn.eu/d/2ucAbrR

Or a lot cheaper with power monitor: https://nl.aliexpress.com/item/10050054 ... ry_from%3A

Hi Walter and Kedi,

Al those devices have one downside: they are powered with 230VAC - even though they only have a live connection and no neutral. They are powered by a small current that the module allows to flow through the load, even when that load is "switched off". I am searching for a module that's powered by a battery since I don't have 230VAC available at some of the wall switches.

Peter

What are you switching then? Not 230V?

If you are using Philips hue, this is also a way to control everything and can be used in place of your current switch

It is 'not' powered by a battery, even better. (And work great!)

Philips Hue also has devices you can build into a wall socket, or you can directly control the lights

Philips Hue makes uses of Zigbee (and matter these days)

If you have zigbee already, you can use the above switch and control your devices

Possible cheaper in DIY

Hi,

I don't want to switch the power on and off with the module, but send signal via Zigbee to Domoticz when the switch is pressed. That signal activates a script that for example switches on smart lamps. Thus I am looking for a module like the one Thorgal suggest but not at 75 euro a piece. Thorgal, you suggest DIY. Do you have any examples? In fact the solution with the door & windows sensor is some kind of DIY and I can buy 5 or 6 of those modules for the same price. Maybe I should stick to those sensors...

Peter

Maybe something like this:

If you only want to use the switch as a trigger for a script and not really switch something you can use the battery powered switches as gizmocuz already explained. You only have to replace your real switch with the new ones.

The one from @Rik60 is cheaper than mine ^^.
Else in DIY mode, I haven't keep the page, but it's easy, the guy just take a cheaper switch from ikea or Xiaomi and have solder 2 wires on contacts, connected to their existing switch.

Cheap, all switch stay same.

Problem, the 75 euros module can work with one postion switch (push) or 2 positions switch (on / off), the DIY method support only the one position, so you need to found a push switch like the ones you already have (if it's a 2 positions)

Walter, I don't want to mix different kinds of wall switches and outlets. That's why I was looking for a module that fits invisibly behind an existing wall switch. Apparently they are only available at 75 euros each...

So I changed plans.

I ordered four door & window sensors from Aqara (the old type MCCGQ11LM). I already used them before and they work well 99.99% of the time. The existing switches are transformed to pushbuttons by adding a small spring. They are smaller then the Ikea or Aqara buttons so you can have two of them behind one switch. They are also easier to wire up. The only disadvantage is that they only recognize On and Off and can't handle multiclicks themselves. I solved that with a dzVents script, see Using an Aqara door sensor as a selector switch.
