XIAOMI Aqara Two-way Relay?
Hi everybody,
I’m currently looking for a cheap wifi switch which works OOTB with the raspbee plugin and the ConBee II stick, like the OSRAM Smart+ Plugs, but with cabel clamps, for installation within the wall.
My question: Did someone already test the XIAOMI Aqara Two-way Relay?
Or has someone another tip which wifi switches work OOTB with raspbee/ConBee II?
I guess the sonoff switches are not working OOTB, right?
Thanks in advance 
the sonoff switches use wlan and not zigbee. and i would say you have to flash them with tasmota to use them. then u can address them via mqtt.
@Pedder
I prefer and can recommend the shellies for all in-wall use !
-> shelly
shelly1 (10€)
shelly1pm (with power consumption measurement) (15€)
shelly2.5 two-way relay with power measurement ( 20 €)
These are super easy to integrate with MQTT in Pimatic,
either with OOTB original firmware or, as I did, flashed with Tasmota, which is easy to do.
but these relays are wifi based and not zigbee.
for normal switchable power plugs I also prefer WiFi.
my favorites are the
gosund sp111 (with tasmota flashed)
~10€ with power consumption measurement
@kosta could you please tell, where you get the gosounds for 10€? looks a like a tiny alternative.
Hi @kosta and @quotschmacher,
thanks for your answers and sorry for my fault. For sure I meant Zigbee and not WiFi, … to use them simply with the existing equipment.
Reason is, that the communication with my 433Mhz Intertechno switches in the garden often fails, and a 12h running pool-filter is needless 
About sonoff I already read here in the forum, that they also have to be flushed, so that seems to be similar to the shellies, respectively I would have to install one further plugin (MQTT).
So what I‘m searching for, are switches like the shellies, but as simple to integrate like the Osram Smart Plugs, … without removing the electronic parts out of their casings
Hmhmhm,
after I did some research in the internet, I think I got now the point, why you are not using Zigbee switches (as I learned, according to the Zigbee Light Link (ZLL) standard).
They in minimum cost more than 20€ per piece, mostly starting at >30€ … 
… and about the cheap ones, it is often unclear, if they really work according to ZLL
… I see, I will have to spend some research on MQTT and flushing sonoffs or shellies …

i think here https://github.com/arendst/Sonoff-Tasmota/wiki you will find a lot of knowledge…
Hi folks,
as I currently do not find the time to dive into addtional standards (MQTT, flushing, etc.) I at least ordered two of those cheap china zigbee switches on ebay:
https://www.ebay.de/itm/Smart-Home-Zigbee-WiFi-Control-Wireless-Switch-Modul-Für-IntelligentesZuhause/401866237846?ssPageName=STRK%3AMEBIDX%3AIT&var=671696387941&_trksid=p2057872.m2749.l2649
Paring to deconz was a bit tricky with the first one, but the second one worked right fast.
So as an alternative I think they can be used well.

Hi folks,
just for the books.
Delivery and testing took a while, but the XIAOMI Aqara Two-way Relay works fine.
Simply discovered by the Phoscon App and now steered by my ConBee II.
As both built in relays can be switch independently, for sure for shutter steering usage, a respective rule has to be set up, to prevent that both are switched on at the same time.
As it is not really small (50x46x24mm) I fear that it will not fit into a normal wall switch hole.
