Add a light switch to Aqara Hub (v3 gateway)

I bought an aqara hub and a couple of ‘no neutral’ light switches to test, because they look nice, and if they’re decent i’d like to install them all around the house.

I’ve added the gateway to HASS, and can see and switch the built in light of the gateway.

I call the ‘add device’ service from HASS, the hub speaks in chinese. I’ve tried holding the light switch button for 10 seconds, and the hub does say something in a more quiet chinese voice. I can’t see the switch in HASS however. Discovery is on. Do I need to add the switch manually somehow?

I’ve noticed the switch does appear in the Aqara Android app, but not in HASS. I’ve tried removing it from the app, and re-adding through HASS, but same result. I can’t view any options or settings for the bulb in the app (such as extracting an ID for the switch) so I can’t attempt to manually add it. I can’t view the options because of a firmware upgrade prompt, but having read a few posts on here am worried about upgrading to the latest firmware. I’m currently on 1.4.1_150.

Thanks for any help in advance - I don’t want to have to start looking for some other ‘no neutral’ light switches!

Hi, sorry, how did you add the Aqara Hub to Hassio? I’ve read that there is no “dev mode” yet, so the configuration key can’t be obtained.
