I got a ZBMINIL2 for a particularly finicky switch installation (no neutral, tiny outdated electrical box). It seemed to work fine for about a year and a half, and then started falling off my network. I figured okay, maybe something happened to it, no big deal, I'll order another one.
I got it, installed it, and... same thing. I do a reset, add it to my hub (C7), and it works fine for maybe half an hour and then... just falls off again. I've tried it with both the "Generic Zigbee Switch" driver and the custom "Zigbee - Sonoff - generic Relays/Outlets" driver that someone recommended for I think it was the ZBMINI-R2? And it still falls off.
I've now switched it to an Aurora Zigbee Switch and it seems to be hanging on a little while at least (2 hours and counting thus far), but if that too fails, any ideas? It's weird that it worked for over a year, and then just suddenly doesn't want to play any more, and it's not the specific device because I replaced that.
After you install the driver manually and change the 'type' to the 'Tuya Zigbee Switch' driver, select 'LOAD ALL DEFAULTS' from the Configure dropdown menu and click on the Run button (Configure button on the old UI)
Thank you for this driver. I always appreciate a dedicated driver rather than generic drivers. I assume that the driver also includes a profile for the ZBMINIR2 switch?
I am having the same issue. it's driving me nuts. same scenerio as you. worked great, stopped working, bought another, disconnects after an hour. keep us posted .
same here. multiple ZBMINIR2's and one ZBmicro using @kkossev 's fantastic driver.
they work great initially then seem to drop off after a period of time perhaps 30-60 mins. mesh was stable before updating older devices to these ones. @kkossev how hard would it be to add a firmware update button to the driver? i found a repo with Itead firmware updates. (i don't know if firmware will fix the issue, but i'm at a loss on how to resolve without buying a Sonoff Bridge ... which i really don't wanna do).
Adding an 'Firmware Update' button will require just a few lines of code, but it will not work if the OTA images are not uploaded to Hubitat OTA repository in the cloud.
@mike.maxwell is it possible to add the OTA updates from the link above?
@sanewton72 can you test whether the Sonoff ZBMINIR2 switches work in 'Relay Detach Mode' with the latest driver version?
happy to try, but...
i actually have smart bulbs so have always wanted a detach relay feature, but there was no way to do it previously without going to the ewelink 'dark side'.
so the 'switched active wire' (that feeds the bulbs) is NOT connected to the 'L out' terminal on the ZBMINIR2: the bulbs are permanently and directly connected to the circuit source ('L in'). When the button is pressed I use a HE app to mirror the switch state of the ZBMINI2 to the smart bulbs. Hope this all makes sense in verbose text.
so i'm wondering out loud how effective a test will be without the bulbs actually connected to 'L out'? thoughts? happy to do so if you think it does...its the least i can do to help!
Thank you for the reply, Roger. I have followed up in the linked R2 thread, as now I realize the OP thread topic was about ZBMINIL2, I didn't mean to derail it.
I finally managed to give this driver a try the other day. Interestingly, the ZBMINIL2 seems to periodically try to come back (we turn on/off a device group the switch is a member of and the switch activates appropriately, after several hours/days of not responding, but then 30-60 minutes later is back to not responding). I can even see in the state variables, "Last Rx" shows {"timeStamp": "2025-03-19 03:54:32.706"} (which was about 6 hours ago) despite not having messed with it for a day or two.
I tried changing channels after doing a channel scan; my hub was operating on channel 20, there seems to be something else on channel 25, so I dropped down to channel 12... I don't know if the driver switch or the channel switch is what resulted in the ZBMINIL2 coming back periodically, but regardless it still ends up being unresponsive a majority of the time.
No, I mean just downloading the raw .OTA files from the GitHub repository and uploading them to Hubitat cloud repository ... if the binary format is compatible and if the *.OTA files is all we need.... I don't know.
i tried the driver you posted. still does the same thing. Works for 30 min to am hour then stops working until i go push the button on the relay to get it to connect again. i give up on this thing..
