Do you know how to go to the zigbee2mqtt web page?
There is a link in the zigbee2mqtt integration. It’s just to see what value is actually being read by zigbee2mqtt.
That would help us understand whether the problem is Gladys or zigbee2mqtt
No, it’s an option to check the availability of your devices and here in your case the option is Disabled.
In my opinion it’s more of a connection problem with your dryer’s plug. Because with an LQI of 0, the plug and your dongle are having trouble communicating
You should consider moving your dongle, placing it further away from the Wi‑Fi antennas…
@G_rom0304 If your home is « complex » (large, with thick walls), or if there are interferences (lots of Wi‑Fi routers in your area), Zigbee can struggle if you don’t have a sufficient mesh of devices.
In Zigbee2mqtt, you can see a map of your network with the link quality between each device (LQI in English). If the link quality is low, you need to strengthen the mesh by adding repeater nodes between your Zigbee USB stick and your end device.
At my place, I have 41 Zigbee devices, 15 of which are routers (notably all my IKEA bulbs), which makes a great mesh I’ve never had any issues!
