Smartify existing (German) light switches, ideally Matter-over-Thread; Matter-over-Thread bulbs

[lime wolf]

**The goal: **

I have 3 lights in my Bedroom: 1x e27 ceiling light, 2x e14 nightstand lights.

I want to make the existing light switches in the room smart, and make them turn on all the lights, brightness depending on time of day.

I might also add battery powered tread / zigbee switches to the nightstands with more buttons, to only turn on one / both nightstand lights.

I have mostly matter-over-thread devices from eve right now, and that works well for me, so i'd like more MoT if possible.

I do have zigbee available too, if that is not an option.

What I want to buy:

I basically want something like https://sonoff.tech/en-de/products/sonoff-mini-extreme-wi-fi-smart-switch-matter-enabled, but I'd prefer it to use Thread instead of WIFI.

Does this exist?

As for lights: I like the aquara T2, but they don't come in E14 size. In E14 I only find Wifi bulbs, nothing with thread.

I'm thinking of just going with ikea (zigbee) bulbs everywhere...

It looks like there are a few matter-over-thread relays available, e.g. https://www.sunricher.com/matter-thread-relay-modules-sr-mt9101sac-hp-switch-b.html or https://inels-wireless.com/shop/matter-en/switch-unit-with-inputs-for-external-buttons-matter-rfsai-62b-sl-mt/ but I have no idea if either is available in germany, or whether they support a decoupled mode for use with smart bulbs

Nice to see some made by a czech brand, I just sent them an email to see if it does what I want.

IKEA sells ZigBee remotes that works for on/off/up/down

https://www.ikea.com/es/es/p/rodret-regulador-inalambrico-inteligente-inteligente-blanco-20528128/

You can buy it in Spain also in a pack with a ZigBee smart plug for 10€

The plug also works as a ZigBee repeater. And once integrated in HA, it's transparent the underlying tech, no "matter" what (pun intended 😂 )

Right, but I want to turn my exising wall switches into smart switches. No batteries etc.

I'm sort of allergic to battery powered tech, especially for things that stay in fixed places.

As for the switches with more buttons, I will probably buy two of these tho:
