Seems like the SNZB-02 in general has issues based on the thread and such, I currently have the SNZB-02P that has been working without issue… so far, paired through ZHA on the skyconnect.
The thing is: are you questioning the device because of a zigbee issue that comes from your mesh which results in connection loss/having to repair or the accuracy of the sensor.
If you are running a zigbee network, you know that it’s not that obvious to have a reliable mesh.
In my HA, I am running Zigbee2MQTT version 1.40.2 with a EmberZNet coordinator on a flashed Sonoff ZBDongle-E.
My Sonoff SNZB-02D H-T sensor is not consistently updating Temp and humidity consistently 3/4 times an hour as seems to be the expected default. There are long, 3-5 hour periods when I receive no updates at all.
The Sonoff HT sensor is located about 6m from the Zigbee coordinator and it displays a fairly good link quality of 118.
Anyone else having the same problem?
I am using an automation based on THIS to manually poll all SNZB-02 sensors every 5 minutes. Works flawlessly.
trigger:
- trigger: time_pattern
minutes: /5
action:
- action: homeassistant.update_entity
target:
entity_id: >
{{ integration_entities('sonoff')
| select('search', 'temperature|humidity') | list }}
I have the very same behavior, but its the humidity that gets updated only once after pairing. Did you find a solution?
Try a new battery regardless of what the battery % the sensor tells you.
Mine said 72% battery, and still have iirc 3v when I use a multimeter to test the battery. So out of desperation I went ahead and used a fresh battery.
Et voala. It worked, at least for me.
Oh and btw, I have since changed the sensor readings reporting frequency & threshold.
