Any metal works/blacksmith would extend the spindle for you. It's a five-minute job.

May I ask what walll switch did you use for the Fibaro Jalousiensteuerung?
Thank you

Following on from this a little bit, replacing the existing switches. Have people used or heard of Sonoff? They have relays and all sorts of accessories, but I quite like their wall switches.

Do you think the EU switches will be compatable with the switches here?

Ciao.
I was looking at ways to keep the same light switch yet adding smart functions. At first I thought about the Shelly devices, but do they fit in the small hole behind the switch/plugs?

If so, which one of them would add the capability to be controlled via Zigbee?

Thanks for your help

Sunricher make zigbee switches that get mounted behind the existing switch. They make dimmer/switch modules too to use with dimmable LED or halogen lamps.

They're also compatible with Philips Hue so can be controlled that way too.

29 CHF at the moment for the basic switches from Brack.ch

Funk-Schaltaktor ZigBee 3.0 400 W

Thanks. How is this different from the Shelly?
I do not have Hue or Alexa, but I guess this can be implemented in Home Automation. I have HA running in a raspberry with the Zigbee module.
Also does this require the "Live"? In some switches I may only have the neutral.

If you have only the neutral then something is wrong with your wiring - it used to be considered OK to switch the neutral wire, but that hasn't been for a long time.

Having only a live wire is relatively common at the switches of multiway lighting circuits though.

Yes, sorry, then must be only the "live" in the switch (I am not an electrician, sorry ).
And yes, this is probably part of a "multiway" (more than one switch operate the light), at least for some lights in my house.
Would this work?

Shelly is WLAN. The one I showed is zigbee.

Yes. That would work.

Every circuit needs a live and a return path (neutral). These modules need both.

For a multi-switch setup - you could put a zigbee module in every switch and control the switching in code.
This would be a bit messy.

What if I put the module in the ceiling light itself? This way I should be able to override the multi-switch complexity, right?

If you were going to go down that path, you may as well just keep everything as it is and fit a Philips Hue or similar bulb and forget any switching module - the end result would be the same.

The problem with that though is that if someone turns off the lamp at one of the existing wall switches, you won't be able to use automation to turn it back on.

Is there a particular reason to want to automate it?

I already have 2x philips Hue bulbs (bluetooth) in one ceiling lamp, and other Yeelight in others.
What I would like to achieve is:
1) use the existing wall switches to turn them on and off
2) never cut the power off to the lamps, so that I can always control them from HomeAssistant.

I thought that adding e.g. a Shelly, I can keep the existing wall switch, and it would be the Shelly controlling a) the fact that the power never gets cut off; b) using the input from the wall switch only to toggle the status.
Additionally I thought that by putting the Shelly in the ceiling lamp, I would not have to find a complex way to control via code 2 different Shelly's in a multi-switch system.

If you have a permanent live and neutral in the ceiling above the lamp (it's possible one passes through (especially if it feeds a socket further on), then you could wire the module to that and the switched live from the switches to the switch input of the module.

That would work.

if it passes through, does it impact anything? my understanding is that power is anyway never cut off?

It is cut off to a lamp - otherwise the lamp would could not be turned off.

I don't want you to get out of your depth here so don't really want to get into details but you definitely shouldn't do anything you are not 100% certain of with mains electricity.

Ahah, appreciate the worry.
I have been dealing with these type of things throughout my life so it should not be an issue but I see where you are coming from.
My flat has been heavily refurbished 3 years back but the electrical system was probably not touched: one day I wanted to make a change in the kitchen and I could not understand why the motorized blinds in the opposite side of the house were not working anymore, so yes, I agree with you that I could mess up with things, also because the system is old and complex.
I will see if I give it a try.

Thanks a lot!

started my journey in home automation.
got alexa first.
tied it in to my samsung qled.
next up i added hues...and realised i need a bridge...so i ordered that.
next step is to replace dumb switches in my apartment with smart ones.
lastly i wanna do thermostats and blinds controllers...its quite a fun learning journey.

Hello all!


I'm just starting a major redecoration at home and I'm really interested making it smart


I'm wondering are there any certificates required to fulfill by a smart home products vendor to securely work with 240V and be installed into that plastic wall box and hidden (like Zigbee Mini from Sonoff).


I see most of the producers have CE certificate of conformity, but is it enough here in Switzerland? I'd like to be sure if I install some switches and other stuff into the system, it will be then signed off by an electrician during a required approval test after the redecoration (and then every 10 years also)


Do you have any experience in that matter? Any hints where to check such requirements?


Thanks!

CE is fine for Switzerland.

However, CE is a self-certifying mark. You may want to practice due diligence and confirm that a manufacturer actually has test data to back up the mark.
A manufacturer should have a link to CE/FCC data on their website.

Generally, if the product is available for sale in Switzerland, it will have been approved.

The Sonoff Mini Zigbee is certified. Link

If you do decide to home-automate your home, this is what I have learned:

Make sure everything will still work (or aren't important) without the home-automation system and choose control devices accordingly.
For example, I've got some 'behind-the-switch' zigbee dimmers for lighting and with the home automation, I can dim them via Alexa or turn them on when someone comes in etc etc but without the zigbee network, they appear, to the user, to be normal Feller push button switches.

Make sure any control device is rated to, or above the power demands of the socket/light fitting. You don't want someone else to plug a higher wattage device into a socket and cause overheating.


If you have any questions, ask here!

Hi Tom1234,


I didn't expect such prompt response, thanks!


An electrician I talked to was rather concerned with that Sonoff switch I showed, asking if it is "Chinese"
I bet 70% of his car is also Chinese he is not even aware about...
But if CE is enough, I hope it will be fine.



Thanks for the hint about switches. Actually I plan to have switches which are wired and work without and network, and wifi/zigbee controll is a "feature". Sth like this:
https://sonoff.tech/product/smart-wa...ich/tx-series/
It requires no battery, which is great from a maintenance perspective (and more ecological i hope)



But maybe from your experience Tom1234 I should go with another ecosystem, better fitting Swiss constraints (like those wall boxes with diagonal attach screws, instead of orthogonal like EU).


I will definitely ask here more, I promise
