Sonoff S26R2ZB compatibility?

Confused_Penguin · October 20, 2021, 10:09am

Hello there!

So I rather hastily bought a pack of these babies

Looks like they come in UK and EU flavours and they're super cheap. I see people just buying them to extend the zigbee network, though I am intending to use them as switches.

Anyway, they list Samsung and a bunch for compatibility, not habitat though that's not very surprising. They discover and putting them on Generic Zibgee Switch shows a status, but they don't seem to respond to On and Off

Anyone else had luck with these guys?

Did you click Configure after changing drivers to Generic Zigbee Switch?

Confused_Penguin · October 20, 2021, 10:19am

I did not, good spot. Just tried that now though and it's no better.

The status changes nicely in the UI when I press the little button on the gizmo, but no luck the other way around.

Possibly a bit late now that you've already bought the Sonoffs, but the SmartThings UK Socket is recently around £16 on Amazon which is a steal for a great quality socket that also supports power metering.

Confused_Penguin · October 20, 2021, 10:36am

Well that is interesting, I'm certainly not beyond sending them back and getting those. Seems a shame though, so close.

Confused_Penguin · October 20, 2021, 10:38am

Also, these suckers are £25.65 for 4, that's like £6.50 each! But that's very expensive if they don't work

could you try another driver? There is some nice Sonoff outlet support in this:

Confused_Penguin · October 20, 2021, 5:15pm

Thanks for this, what repo does that come from can I ask?

I did try it, I don't this that's any better I'm afraid.

The fingerprint stuff - This great driver queries the device and creates a fingerprint of what the device can do, it originally asked that you send that info to the developer so he could add it to his driver to build a list of sorts. He is no longer directly supporting this driver!
Don't be put off by the log messages, they were there to help during this identification process - the driver will still function - I should have warned you'd see that but to ignore it.
I have some devices that didn't work well with the generic drive and switched to this and it solved me - I was just hoping you might benefit as well. It comes from this Github Repo:

Confused_Penguin · October 20, 2021, 5:39pm

Sir! You are a genius!!

I used the generic switch driver from that repo and it worked like a charm!

Thank you for helping me out. Now I think all should buy these for £6.50 a pop and pimp your sockets with this driver !

jshimota · October 21, 2021, 6:28am

awesome! so... I will note why I'm so aware of that driver. - It has a Presence built in which is totally cool. it will refresh automagically. I myself modified it so it didn't show up as a Presence device when I was building rules. but Yea. Markus is a genius and I'm just plain glad to help someone by pointing it out.

levanterman · January 22, 2022, 2:32pm

Hi, this is also worked for me which is brilliant, but child devices were created for the single socket. Did you get child devices? If i disable the option 'Enable Multi Endpoint Discovery' then the switch stops responding to ON/OFF.
Will having fake Child Devices use up the total Device count?
Thanks

Confused_Penguin · January 24, 2022, 1:16pm

I did get child devices, I was content to leave them. I can't talk to the total device count I'm afraid.

Hi @Confused_Penguin I too have some zigbee Sonoff S26 plugs that I want to connect. Although I'm not entirely new to home automation, I'm very new to Hubitat (so far I have only installed natively supported devices) and I would appreciate your guidance with one step of getting this to work.

I've installed the T4HE Tasmota for Hubitat Elevation app and drivers from markus-li, as you recommended. But how do I now add an S26 plug in Hubitat? I have clicked to manually add a device but what should I do to "make sure the device is connected to your wifi"? What do I put for the IP address in the below screen?

Thanks in advance!

Ranchitat · March 4, 2022, 7:10pm

The S26 Sonoff Plugs come in WIFI, aka Tasmota (ip needed).
Or S26R2ZB - ZigBee (different DRIVER ) also available on HPM.

DanielAustin · March 4, 2022, 8:54pm

Oh, d'oh! I did think it rather bizarre that any zigbee device should be connected to wifi in some way. I was aware Sonoff also make a wifi version of this, but stupidly it never even occurred to me that they would have called both of them S26 – one model just with a suffix! Thanks for the pointer to the other driver

Inge_Jones · June 11, 2022, 2:34pm

The suggested driver isn't doing it for me. It works for a few minutes, during which time it's spamming the log every 10 seconds exactly - unless I turn off logging altogether. And then it stops responding to on and off commands and I have to re-pair it.

kkossev · June 11, 2022, 2:57pm

Searching GitHub for S26R2ZB reveals tons of complaints about Sonoff S26R2ZB performance, especially on its Zigbee routing functionalities... Better to be avoided IMHO.

Inge_Jones · June 11, 2022, 3:05pm

As it happens I have a workaround! I paired it to my Hue Bridge which turned out completely trouble-free and shared it to Hubitat that way Not my favorite solution as it feels kind of "messy" but I'll survive.

Inge_Jones · September 22, 2022, 1:03pm

Spoke too soon. It repeatedly becomes "unreachable" even with Hue. And Sonoff themselves claim Hue compatibility. At this rate I am not sure I'd even trust it with the Sonoff hub.
