Dear fellow HA users.
Since about two months I’m running my first HA installation, and while I generally like HA very much and still believe it’s exactly what I need, I’m more and more frustrated with Zigbee “runtime issues” I’m unable to debug myself, simply because I’m a novice and don’t know how exactly to tackle it.
I’m using the latest HA Core 2025.1.4, running under Ubuntu Server 24.04.1 LTS in a “Home Assistant Supervised” setup on an old Dell Latitude D630 laptop with a Intel Core2 Duo CPU T7250 @ 2.00GHz (usually >90% idle) and 3 GB of RAM (only 1 GB used by processes). As a Zigbee gateway I’m using an SMlight SLZB-06M (core firmware version: v2.7.1 (latest stable), Zigbee coordinator firmware Revision: 20241127 (latest)) connected via ethernet, running on Zigbee channel 25.
The issues I’m having are the following (in order of decreasing priority):
- A particular Osram Smart+ plug (mfr/model
OSRAM Plug 01
) is acting up in that it very briefly “flicks on and off” for a fraction of a second every 10-30 mins or so (nothing in the logbook about it). This is annoying, as it causes the lamp connected to it to “flash” briefly, which on the long term may be a threat to the lamp itself, but also to the plug. - Several Zigbee devices (not just end-devices, but also routers) often drop off of the network for several hours, until they eventually come back. This is very surprising, as I have many repeaters deployed all over my house, so it’s very hard to imagine there is any area with a “weak” Zigbee network. (I have 4 floors, cellar, ground floor/basement, 1st floor, roof, and on every floor I have multiple repeaters all across the place, namely OSRAM Smart+ switches, Sercomm/Samsung SmartThings sirens, and Tuya TS011F plugs)
- One
samjin.multi2
(SmartThings multi-purpose sensor GP-U999SJVLAEA) doesn’t update it’s temperature reading (but LQI and RSSI are continuously being updated!) - One Aqara humidity/pressure/temp sensor (mfr/model
LUMI lumi.weather
) reports just a single sensor value (pressure, in a continuous way!), and the others are shown as “unknown” (see this post of mine for more details)
I would be extremely grateful if someone could direct me how to approach these problems. Pointing me at certain HA documentation pages is fine, but please make it specific enough and don’t just say “read the docs.”
I’m happy that I made the move away from SmartThings after so many years and don’t want to go back – please help me stay.
Thank you in advance.
Best,
Ralf
