I recently bought an Airbnk M510 smart lock running on Zigbee protocol.
I like its minimal design and that I could just replace the deadbolt butterfly knob with the smart lock and that’s that. Also, it’s the cheapest I could find.
I can connect it to smartthings but it’s recognised as a thing. I tried several device handlers that Smartthings had to offer and added some device handlers I found searching around. So far I haven’t gotten things to work.
I can only use it with the Airbnk app via bluetooth.
Have you tried the ST DTH called “ZigBee Lock Without Codes”?
Also, the door lock zigbee cluster is missing. It should include “0101” in the fingerprint, which is likely going to be a show stopper for you. Knowing this is a Tuya device, and they use a manufacturer specific Zigbee cluster, "EF00 ", you’re more than likely going to need a custom DTH or Edge driver put together, if there isn’t one already.
While Tuya and others love to advertise “zigbee” on their devices, some will work out of the box; but most will require something custom to gain full functionality, or even all functionality, since they’re using a manufacturer specific zigbee cluster (which is completely OK for them to do).
I thought that may be the case because your device is missing the zigbee lock cluster ID I mentioned above, so that will definitely keep you from being able to use the DTH’s you’ve already tried. The lock commands are likely all done through Tuya’s specific zigbee cluster.
There are a few discussions in the community working on Edge drivers, so maybe one of the developers there can help put one together for you. Here’s one of them, but it doesn’t look like he’s addressing locks yet:
I have now added the lock back to a tuya hub and I have Smartthings import any devices from the Smartlife app. Altho it did transfer several lights and some outlets, it doesn’t transfer the lock. The same goes for a ZigBee smoke detector.
I manage to get some information regarding communication protocol from Zemismart that also sells ZigBee locks that works with Tuya cloud. You are welcome to review. Please note that the translation from Chinese to English was done by me with Google Translate, which is not prefect.
I think I found a step closer to get this thing to work.
This thread has an edge driver that deals with EF00 cluster devices like this AirBnk door lock and I got an EF00 smoke detector working with smartthings using this method. So there’s a chance this might work for this door lock also.
After connecting the door lock to smartthings I get this with the above mentioned edge driver:
Unfortunately there are no datapoints shown for the door lock so I’m stuck trying to figure out what to do next.
The protocol described in this post:
… hints and talks about different datapoints that might be useful if trying to decipher this lock. I’ll try my best to fiddle with this driver and post my findings but I’m not sure if my brain is up to the task so any help is appreciated.
