Xiaomi Honeywell Smoke Sensor

This is something I was a little bit excited for. It seems it’s difficult to get hold of but I am happy that I have. I will start with the unbox and add to Home Assistant video, then will build on some of the points raised at the end of the video.

Testing

One of the idea’s that I raised in the video was automated testing. After finding the command for testing in the Hubitat Groovy driver, I was able to then use the ZHA Set Zigbee Cluster Attribute service to initiate a test. The data required is:

ieee: 00:0d:6f:00:05:7d:2d:34
endpoint_id: 1
cluster_id: 1280
attribute: 65521
value: 50397184
manufacturer: 4447

A few moments after calling the service, you will hear the sensor beep indicating it’s still alive and kicking. Simple enough, but lets make this a smart process. Automate it:

  - service: zha.set_zigbee_cluster_attribute
    data:
      ieee: 00:0d:6f:00:05:7d:2d:34
      endpoint_id: 1
      cluster_id: 1280
      attribute: 65521
      value: 50397184
      manufacturer: 4447
  mode: single

This will go through and make an announcement on the small Bluetooth speaker that I set up in a previous post stating the alarm test will begin and advising to listen out for the beep. It’s scheduled to happen once a week on a Monday at 09:15.

If I manage to get hold of more of these, I will run through a cycle and announce which alarm is being tested so I know where to listen out for.

Battery Alarms

Below are two alarms, first one triggers when the battery is at 15%, basically prompting me to make sure I have a CR123 battery ready, the second is firing at 5% to basically swap it out. After all, the last thing I need is for it to hit 1%, go to fire off and then die so switch it out before it’s flat.
