LYWSD03MMC cannot reconnect to repeater

[mmib]

Have LYWSD03MMC with 04 Sep firmware. It works fine until repeater got down (e.g. electricity outage). After this device do not automatically reconnect to repeater. Do reconnect after reboot (remove and insert battery). Other devices (soil moisture sensors) connected to the same repeater works fine with no reconnect issue.

not sure how it can help? Maybe I explained the problem a bit unclear. Binding was ok and device is working and it do reconnect after battery jerking. However it should reconnect to network automatically without any manual work like other devices do.

This behavior is not observed with a normal Zigbee coordinator.

1. In ZigBee 3.0, a maximum time is set before a device is excluded from the network if there are no responses from it. This is not a function of the device, but a function of the coordinator and repeaters.

2. After the ZigBee network drops, the thermometer searches for the network every 3 minutes. This is done to minimize consumption when there is no ZigBee network. But still, in this mode, the battery consumption is much higher.
   Some battery-powered devices drain their battery to zero within a few hours when the Zigbee network goes down. Searching for a Zigbee network requires a lot of power from the device.

3. The Zigbee network is not designed to have the coordinator and/or routers disconnected. Install a standalone router. Otherwise, 90% of your devices will periodically disappear from the unstable ZigBee network. This is Zigbee disease...

4. Check if your Zigbee coordinator is performing the Rejoin and re-binding function correctly. Check if all commands go through the routers.

Okay, thank you. All other devices do not have such issue, that's why I thought something could be tweaked/fixed in firmware.

When testing the coordinator shutdown for more than a day, the Zigbee Xiaomi aqara sensors always fell off. Others did not.
When using Tuya repeaters in Smart Sockets, devices were more often observed to disappear from the ZigBee network...

tweaked/fixed in firmware.

Tell me what needs to be fixed if everything works as it should.

In the year since the installation of the autonomous ZigBee router, not a single device has dropped out of the network.

And once again - the Zigbee network is not designed to work without a coordinator. Devices begin to search for the network chaotically. And if they come across a crooked router from Tuya, then anything can happen.

The same applies to Zigbee coordinators. If the program does not work correctly or does not allow re-join and re-binding at all, then all Zigbee 3.0 devices are disconnected. Tuya and Xiaomi devices do not comply with Zigbee 3.0 standards and require special programs on the Zigbee coordinator side.
