Driver support for Aqara WS-USC02 Smart Light Switch (No Neutral, Double Rocker)

[jlupien]

Hey folks, I have a couple places in my house with a 1-gang, 2-switch setup (e.g. bathroom fan + light). I found the Aqara WS-USC02 devices (Aquara site, Amazon) and they looked promising so I bought a couple and installed one. After having scoured the forums, I now see Aqara/Xiaomi integration with HE is tricky because of the devices' non-compliant implementation of Zigbee. Nevertheless, a lot of Xiaomi/Aquara devices have drivers, but I've yet to find one for these particular switches.

A few related threads:

[Deprecated] Xiaomi / Aqara ZigBee device drivers (possibly may no longer be maintained)

NOTE: Although many users have had great success using them, Xiaomi / Aqara ZigBee devices are NOT officially supported or guaranteed to work on the Hubitat Elevation platform. I am maintaining a collection Xiaomi device drivers for Hubitat in a GitHub repository, at veeceeoh/xiaomi-hubitat. These device drivers are based on the bspranger/Xioami repository of device handlers for SmartThings, but with significant modifications and improvements for use only on the Hubitat Elevation hub platform. …

@markus there is a casting exception in the model DJT11LM vibration sensor driver. It occurs when the Set open and Set closed position buttons are pressed on the driver page. [image]

Xiaomi & Aqara Devices - Pairing & Keeping them connected

NOTE: Although many users have had great success using them, Xiaomi / Aqara ZigBee devices are NOT officially supported or guaranteed to work on the Hubitat Elevation platform. Because of their small size, simple design, and relatively low price, the Chinese home automation (HA) market ZigBee mesh network-based devices from Xiaomi / Aqara have seen an increasing level of popularity in other countries, where users are attempting to integrate them with their HA hub platform of choice, instead of t…

I've tried some of these drivers. The one for QBKG03LM did seem to be able to create child devices, but I couldn't control them or see their state.

Is anyone aware of drivers for these particular WS-USC02 switches? If not, is there any hope of creating one, or has someone already tried and deemed them a lost cause? Lastly, I've not written any drivers myself, and have limited prior Zigbee protocol knowledge, but I should be capable. So any pointers in the right direction for how to start debugging or reverse-engineering these devices would be much appreciated. Could be a fun new hobby for me.

And lastly, if none of the above works out, does anyone have any other recommendations for double-switch solutions. Hard-wired, neutral is available.

Thanks in advance!

Considering just switching to the Zooz ZEN30. Pretty much all my other switches are Zooz and that's been a good experience. Should've stuck with 'em.

I never did. Switched to Zooz ZEN30 and have been quite happy. Sorry.

Zooz ZEN30

I am in Canada, where do you get Zooz, it's dimmer, I just need on/off switch...

I juts bought one of these and it's working nominally well with the Generic Zigbee Multi-Endpoint Switch driver.

Sadly none of the community based drivers seemed to work very well.
