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

daufinsyd commented 2 years ago

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

I have a sonoff s26R2ZB and I have the same problem. My plug disconnects after 1 or 2 days. The coordinator I have is a zigstar stick v4 it is flashed with version CC1352P2_CC2652P_launchpad_coordinator_20220125.zip. I don't understand how ota updates are and if they are done through zigbee2mqtt, but in mine ota it appears empty

daufinsyd commented 2 years ago

Since Sonoff sell those USB Dongle to work with zigbee2mqtt, shouldn't they have interest in delivering OTA Updates via z2m ?

Very good point, maybe off-topic but curious if Koenkk is in contact with ITead about having OTA provider in zigbee-herdsman?

I do not expect that ITead would code that OTA provider themselves but instead that they would provide a public OTA server and/or public OTA links Sonoff Zigbee OTA Firmware images that any open-source Zigbee implementation/application could make use of.

Such a would be of interest to not only Zigbee2MQTT but also to other popular open-source Zigbee implementations/applications such as IoBroker (which also depends on zigbee-herdsman), zigpy (used by Home Assistant's ZHA integration component, Jeedom Zigbee Plugin, and Domoticz Zigbee Plugin), and OpenHAB, as well as maybe closed source Zigbee implementations/applications.

There is not yet an OTA provider (script and URL-links) for ITead Sonoff Zigbee products for the OTA library in zigbee-herdsman-converters which Zigbee2MQTT depends on, see https://github.com/Koenkk/zigbee-herdsman-converters/tree/master/lib/ota

Sonoff Zigbee products currently have to either be flashed either by resetting the device and pairing it with the proprietary ITead Sonoff ZBBridge Zigbee Bridge/Gateway or manually via a c/JTAG, see https://electrolama.com/radio-docs/advanced/flash-jtag/

@Koenkk Sorry for bothering you, but is there any progress? Should we contact Sonoff separately to try to get a response faster?

Koenkk commented 2 years ago

@vmonkey still waiting for a response from them (although I don't expect they can provide an OTA update)

Yes me too. I have just found this thread and bought some IKEA bulbs and now realise that all my problems I have are with these plugs and not just general Sonoff dongle / Z2M issues. As previously suggested I will probably buy a Sonoff zbb to update firmware (annoyingly I had only just flashed my Sonoff ZBB with Tasmota) but it would be great to find a better way going forward

d0m1n1qu3 commented 2 years ago

@d0m1n1qu3 This should have been fixed in CC1352P2_CC2652P_launchpad_router_20220125, see above posts. Does the problem occur on the latest firmware (I do not find this clear in your comment)?

so i tried some days and found out that the 20220125 works better .. but in device view the router goes offline and got next ping after about 1 hour not earlier :-/ ..

nickwild-999 commented 2 years ago

Would @ptvoinfo firmware work on this? I am due to receive a fresh Sonoff ZBB today so I will see what happens when I try to update the firmware. My S26R2ZB are currently on dateCode:20210923 ,swBuildId:2.0.1

nickwild-999 commented 2 years ago

FYI: I have a fresh ZBB and I can't find any means of updating firmware for the S26R2ZB sockets or the v2 01MINIZB from the EweLink App. IMG_358B30BED3B6-1

Anyone know if ITead has ever released an OTA update to any of its Sonoff branded Zigbee Router or Zigbee End-Device devices?

At least no one has so far as of yet submitted/uploaded an updated OTA firmware image to Koenkk's zigbee-OTA repository:

see #273 where @ptvoinfo confirms only v2 01MINIZB will take his firmware

FYI, @ptvoinfo posted an article about a discovery when flashing his custom PTVO firmware to Sonoff ZBMINI (01MINIZB v2) here:

https://ptvo.info/custom-firmware-for-sonoff-zbmini-01minizb-and-ewelink-switch-zr-02-923/

That article is the conclusion from -> https://github.com/ptvoinfo/zigbee-configurable-firmware/issues/96

Apparently, you need to select the CC2652R chip type and not CC2652P in the PTVO firmware configurator so that it does not try to make use of the power amplifier, because as it turns out that the radio module PCB does not have all the components needed to take advantage of the built-in power amplifier of the CC2652P as the PCB has been optimized/limited by ITead's engineer for use CC2652R. Thus trying to enable the power amplifier will result in a firmware image that while technically runs it can not transmit packages because it should not use the power amplifier on this board so can in practice not be used?

So as a workaround with a PTVO firmware image it then probably very likely that selecting CC2652R chip type in the PTVO firmware configurator will result in a working firmware image on the ITead Sonoff S26R2ZB ZigBee Smart Plug similar to the new Sonoff ZBMINI (01MINIZB) as both use CC2652P (CC2652 P1F) chip model and their radio modules have same design "limitations"?

The tip is that might be a good idea to try PTVO firmware but select the CC2652R chip type (and not CC2652P) in the PTVO firmware configurator to get firmware omage without power amplifier enabled.

@ptvoinfo Do you think that the ITead Sonoff S26R2ZB plug has the same design limitation/optimization and need a CC2652R config or at least need a firmware configuration that does not make use of the power amplifier of the CC2652P to work?

Manually configuring the transmit power to 5 dBm or less in the firmware should probably also work?

While it looks like S26R2ZB (S26R2ZBTPG/S26R2ZBTPF/S26R2ZBTPE) is also based on the same CC2652P (TI CC2652 P1F / CC2652P1F) chip, it does at a glance not have the exact same radio module design as the Sonoff S26R2ZB plug has a ceramic chip antenna instead of a PCB antenna.

I wrote to Sonoff too, and they replied that the issue is not fixed yet and It is under investigation.

@Koenkk thanks for the previous reply and all your effort. I really appreciate that. I have thought about a workaround- is it possible to restart the plugs via Zigbee2mqtt? If yes, doing that on a regular basis (automatically?) might at least avoid the manual resetting.

Zigbee doesn't have such commands, so no.

MattWestb commented 2 years ago

@Koenkk sending one leave with rejoin flag ? I dont know if the device is real rebooting doing that operation.

Koenkk commented 2 years ago

@MattWestb I don't expect that reboots the device

daufinsyd commented 2 years ago

Hi @vmonkey do you have any updates from sonoff ? Should we all contact them ? I bought a sonoff bridge hopping they'll at least release a fix through it.

ChrisLane commented 2 years ago

I sent the following email:

I purchased a S26R2ZBTPG smart plug via Amazon but it disconnects from my Zigbee network roughly every 2 days.
Additionally, the device doesn't seem to work as a router and so will not extend my network range.
I've heard that there's a firmware update for the plug to fix the issue but because I don't have a Sonoff hub, I'm unable to get the update.

Could you please provide a URL for the OTA update to the Zigbee2Mqtt project or provide another solution such as sending me a sonoff hub so that I can fix this issue?
I and many other people are frustrated that I've received a product that clearly hasn't had enough testing and cannot be updated without purchasing more proprietary hardware for this open standard network.
https://github.com/Koenkk/zigbee2mqtt/issues/10282

Received the following response:

Since the issue is not fixed yet, the developer team is still locating the problem.

But they will release the updated firmware of the ZB bridge which is 1.5.0, which might help to fix the issue of the device entering the offline status.

benempson commented 2 years ago

I have exactly the same problem here with my S26R2ZB plugs, disconnect every 1-2 days, unplugging and re-plugging fixes the issue. Following here and hoping Sonoff release an OTA update soon!

vmonkey commented 2 years ago

@daufinsyd I received almost the same generic message as @ChrisLane did. There was no contact from Sonoff afterwards. I do not know whether contacting them separately would help - there is probably nothing to lose though (assuming the customer service is not being operated by developers). At least they would see that they should prioritize fixing it.

daufinsyd commented 2 years ago

I contacted them again:

Dear buyers, we have consulted with the technical staff, and there is no user feedback to us about the problem that the S26R2ZB is easy to offline in ZBDongle-P.
The website you mentioned does not belong to our official website, there is no evidence or statement to actually confirm the problem, and I read the content of the link you said, the developer's wish is to hope that our side will contribute the firmware to users Program the ota yourself, it's impossible.

I'm wondering how many "technical staff" they have tho (@ChrisLane ) I think you are right @vmonkey

Hedda commented 2 years ago

@daufinsyd Can you maybe edit/change original topic subject for this issue to specifically mention the S26R2ZB plug? Suggest:
