For me the door sensor SNZB-04 appears offline after a while in the ewelink app. It goes back online when you open or close the door.
I brought the zbridge closer, switch to hotspot mode, there is nothing to do.
I'm not sure if my zigbee bridge sleeps or turns off, sometimes when my automations dont work I check the app to see it not on my ewelink home page . Give a few seconds, I see it connecting again so it missed its trigger. anyone here having the same issue. I might have put alot of conditions that it 'might' crash?
Attach your jumpers from the Zigbee bridge to the USB TTL (Amazon) or CH340G or (Aliexpress) as follows;
ETX to RX (Note the RX to TX and TX to RX)
ERX to TX
3V3 to 3V3
GND to GND
IO0(GPIO Zero) to GND
Example USB TTL
Plug in the USB TTL to your computer and open Tasmotizer. In the odd case of your antivirus notifying you, it's a false positive. Choose your com port for the USB TTL flasher. Select the Release radio button and choose tasmota-zbbridge.bin as shown below.
Press Tasmotize! and it should start the flashing process. If not check your connections and COM port and try again.
Once the flashing is complete, unplug the USB TTL flasher, remove the wires from the Zigbee bridge, and power it back up via the normal USB power connector. You can also put it back in the case if needed.
Using your phone or computer, scan for available access points and look for a Tasmota-xxxx WiFi access point.

Just gotten Sonoff zigbee and its temperature, remote switch, window/door sensor and motion sensor.
Had a few try to get all connected but someone things are lacking on apps per se.
1) Devices do not show connectivity with the sonoff zigbee bridge.
2) On the apps, its does not show the devices battery level as claim.
3) All devices can be detected by both Alexa and Google home except motion sensor.
4) I had to reset the window/ door sensors ac couple of time . It didn't show battery level low, connectivity issues etc. I had to literally remove the battery and slot it back push the reset button etc. Done twice within a week....
