Sonoff S26R2ZB not able to pair

radino · September 10, 2021, 11:24am

Hi there.
I got this device few days ago. I already have zigbee coordinator CC2531 implemented in HA and few devices connected.

Few issues here with S26ZB:

not able to switch to pairing mode - device is countinously blinking green. Exactly as described here Judging Your Sonoff Status from LED Indicator – eWelink (coolkit.cc) - case section 4
is the device compatible with CC2531?

As this is pretty new device, I can not find much info on internet…

Do YOU maybe have some more info or can you redirect me somewhere…
Thanks.
Rado

What integration are you using ?

only lists tasmota (tasmota2zigbee)

Zigbee2mqtt is not supported yet

don’t know about ZHA.

Thank you Francis.
I am with ZHA right now, but open to use any other integration which is gonna be recommended to me. Already have 30+ WiFi devices, but was wondering how ZB is working.
So what integration would you recommend?

Can’t recommend anything. I’ve been using Zigbee for over 2 years, but never used anything but Zigbee2MQTT (although I have a board for use with zigbee2tasmota, but never got much done but setting it up.)

Any news on ZHA integration for the Sonoff S26R?

S26R2ZB working fine in ZHA here, with a Tasmota/ZBBridge as coordinator

Zigbee2MQTT is listed as supported but it just comes up as unsupported. I also have zigbee coordinator CC2531

Sonoff S26R2ZB Smart Plug Zigbee Router devices by ITead disconnect from network after a day or two - Firmware bug or?

problem

Hello :) ## What happened After a day or two running perfectly fine, routers… kind of disconnect from the network; trying to execute any command results in timeout. It happens for all routers I have (6 sonoff s26r2zb). End devices (sonoff snzb02 / 03) (directly connected to the coordinator) don't appear to be affected. example of failed command: ``` Zigbee2MQTT:error 2021-12-18 16:30:30: Publish 'set' 'state' to 'PLUG-SF-SALON' failed: 'Error: Command 0x00124b0024c08124/1 genOnOff.on({}, {"timeout":10000,"disableResponse":false,"disableRecovery":false,"disableDefaultResponse":false,"direction":0,"srcEndpoint":null,"reservedBits":0,"manufacturerCode":null,"transactionSequenceNumber":null,"writeUndiv":false}) failed (Timeout - 22057 - 1 - 184 - 6 - 11 after 10000ms)' ``` After the router "disconnected", most of the time, simply plugging it off and back solve the issue for a day or two. I tried increasing the TX power but it didn't help, all devices (with either good or bad LQI disconnect). ## What did you expect to happen Devices are working. ## How to reproduce it (minimal and precise) - Join devices - Wait a day or two ## Debug info Zigbee2MQTT version: 1.22.1 Adapter hardware: CC2652RB (from slae.sh, as recommended in the official website) Adapter firmware version: transportrev 2, product 1, majorrel 2, minorrel 7, maintrel 1, revision: 20210708 _Edit: typo_
