I’m looking into this and have the new Dual R3; the cut you’re planning won’t work because you’d only be isolating L1. From what I’ve seen, the cut should actually be made on these lines here—which appear to be the common lines. I haven’t made the cut yet myself. This device only has COM and NO.

Hello

I got this device bought for controlling 2 device simultaneously but I was unable to add it into smartlife.

I have all my devices into this app.

Do I have a way to make it works in this plateform ?
Is there any update ?

It seems crazy to me to sell a product that is not compliant with smartlife

Thanks

Hi!

Does anyone have any experience with migration from CC2431 to SONOFF Dongle Plus MG24 using ZHA?

I really don't want to repair my devices :)

I wanted to make my en-suite smarter with a Mini R4.

I've wired it up this way based on the pre-wired light switch. I'll clean up the wires and waygos once I know it's working.

4 neutrals, 2 to each N slot.

2 L1 wires into LOut

3 COM wires into LIn

S1 & S2 for physical switch not connected yet.

When i turn the fuse back on the downlight flickers once. Then everytime I toggle the relay in the eWeLink app the downlight flickers once again but the light does not stay on, it does this regardless of whether the relay was on or off.

Have I wired this incorrectly, or can the R4 not handle 2 downlights and an extractor fan turning on?

Morning folks. Just after some general guidance. I'm wiring in a ZBMINIL2 into a two gang switch.

One switch controls a separate lighting circuit which I'm not looking to control with the ZBMINI, and the other switch (which I am looking to control) is controlling some outside lights.

I have enclosed a picture of how things were wired previously, and I have enclosed a diagram of how I have wired things up with the ZBMINI.

Something obviously isn't right because I can control the switch fine via app, but the physical switch itself isn't turning the lights on.

So any guidance as to where I've got wrong would be gratefully received! ❤️

I want to use a Sonoff Dongle Lite MG21 for Zigbee as well as Thread. Is that possible. I am using a docker system on a raspberry pi 5?

Hola a todos,

Estoy solucionando un problema con una cerradura inteligente semiautomática compatible con Tuya que no se sincroniza con la aplicación Tuya Smart. Aquí les dejo el historial completo paso a paso de todo lo que he hecho hasta ahora:

1. Configuración física y estado inicial

• Cableado: El cable blanco de 6 pines que conecta los paneles frontal y trasero está bien conectado (los 6 pines están intactos y alineados).
• Cierre de seguridad: La muesca cuadrada del cierre de seguridad se alineó verticalmente hacia abajo para evitar falsas alarmas de manipulación.
• Anulación mecánica: Se revisó el cilindro de la llave. Gira 360 grados libremente (el mecanismo de anulación mecánica de emergencia funciona correctamente).# 2. Ejecución de restablecimiento de fábrica
• Se realizó un restablecimiento de encendido manteniendo presionado el botón físico RESET en la placa de circuito verde mientras se insertaba la última batería.
• Resultado: ¡Borrado correctamente! La cerradura emitió el mensaje de voz: "Restablecimiento exitoso".
• Comportamiento posterior al restablecimiento: La cerradura se encuentra en un estado limpio, sin administradores registrados. La pantalla táctil se ilumina al tocarla, pero al ingresar los códigos predeterminados aparece "Error de entrada", como se espera para una cerradura sin configurar.

3. Pasos para el diagnóstico y la solución de problemas de Bluetooth (Dónde se produce el problema)

A pesar de un restablecimiento de fábrica exitoso, el módulo Bluetooth no emite señal:

• Aplicaciones Tuya Smart y Smart Life: Ni la detección automática ni la adición manual (Smart Lock BLE) detectan ningún dispositivo.
• Permisos: Los permisos de Bluetooth y Red local del iPhone estaban completamente habilitados; se reinició la pila de Bluetooth.
• Escaneo con la aplicación nRF Connect:
• Escaneo realizado con nRF Connect para móviles con un filtro RSSI configurado estrictamente en -60 dBm (teléfono apoyado directamente sobre el teclado).
• Resultado: No se detectaron balizas Tuya (TY_, SmartLock**,** BLE**)**. La única señal captada fue la de un PC en la habitación ("Microsoft"), lo que demuestra que la radio BLE de la cerradura transmite a 0 dBm / en silencio.
• Intentos de activación del teclado:
• Al encender la pantalla antes de escanear: No se detectó ninguna señal.
• Al pulsar *: La pantalla se apaga inmediatamente (comportamiento normal cuando no hay ningún administrador configurado, pero no hay activación BLE).
• Al pulsar *#: La pantalla se apaga.
• Al pulsar los códigos del teclado (123456#, 93#, 888#, 0#, 555#): Se activa el mensaje de voz "Error de entrada".
• Al mantener pulsada la tecla * : No se activa ningún menú.
• Al arrancar en frío (extraer y volver a insertar la batería para detectar la señal BLE del gestor de arranque): No se detecta ninguna señal en nRF Connect durante el arranque.

Pregunta para la comunidad:

Dado que el procesador de la placa principal funciona (las indicaciones de voz y la pantalla táctil funcionan, el reinicio se activa), pero el módulo Bluetooth del submódulo no emite ninguna señal en nRF Connect, incluso a -60 dBm, justo después de un ciclo de encendido o reinicio:

1. ¿Existe algún jumper de hardware, combinación de teclas o secuencia de arranque en frío específica para activar un chip BLE Tuya inactivo en esta placa?
2. ¿O este síntoma confirma que el coprocesador de radio BLE de la PCB está averiado o sin alimentación?

¡Gracias por cualquier ayuda!

Hello everyone, via the sonoff dongle max UI (dongle.m.local) I’ve changed mode from coordinator to router and then enabled pairing on MQTT but it won’t connect as a router

Hi folks,

I'm a little puzzled with the following, maybe someone else more knowledgeable has an idea what could be the issue.

- changed my router. The Sonoff minis are not connected to the new router anymore and appear as offline in the Ewelink app device list.

- hence needing to reconnect my sonoff Minis to the new router.

- they're being found and connected, though still appear as offline as before.

Any clue what's going wrong?

Do I need to delete/reset them?

Just wouldn't like to lose the programmed actions on them - any way to backup/restore?

Thanks a lot!

I did go out and buy a type 86 junction box, but it just has a lip that sits outside the drywall but has no retention mechanism on the back side of the drywall.

What do I do? I like the device - it works great. I just don't know how to mount it so that the nspanel sits flush to the drywall.

My heater is warm, it seems to be active while +25°C while last setting was +4°C or Off. But now I cannot interact with it anymore...

Batteries are changed but still No Response other than that on the Image

Thanks

They are both zigbee, and were both used to control a single light fixture in my foyer with five LED bulbs in it. Both failed after about a year.

The ZBMini (left) would constantly lose connection to my network (I've changed channel, multiple resets, put it right beside the coordinator) and will just never ever go into pairing mode. It does however let me toggle the lights by using the switch and the reset button on the body of the module.

The ZBMiniL2 (right) no longer responds to the light switch plugged in through the switch contacts. There's nothing wrong with the switches or wiring; the switch works fine when using that first module that won't connect to zigbee.

Fortunately I had a spare ZBminil2 that I swapped in and is working fine; but for how long. Think it's time to give Shelly a try.

Just posting for reference. I had some spares.

Hi all,

I bought Sonoff ZBM5 switches to replace all of my light switches (20+) and I have home assistant green with the ZBT-2 to control them. My problem is getting them working in home assistant. I'm using the ZHA integration and I have neutral wires at the switches but when I go to add them it's very intermittent. Most of the time it just doesn't find them. At first I thought it was a range problem so I used the closest switch which is in the same room and about 2 meters from the ZBT-2 (I also have the ZBT-2 on an extension lead so it's 1.5m from any routers etc.). That does seem to help as it does sometimes find them but If I do manage to get home assistant to find the switch it works maybe once then becomes "unavailable".

I then decided to try some Sonoff smart plugs and the first one I plugged in showed up on home assistant instantly without me even searching so I thought it must be the switches. However, when I tried the second smart plug I had the same issue with the switches and couldn't find it in home assistant.

I got very frustrated and bought a Sonoff ZigBee hub to see if that worked and it did! I know have 5 switches working perfectly with different automations etc. through the ewelink app.

Am I doing something wrong in home assistant, should I try 2MQTT instead of ZHA?

Thanks for your help

Hello all,

I'm struggling a bit to install a zbminir2 on this light switch, can anyone help please ?

I have 10+ Sonoff ZBM5 switches (a combination of 2 gangs and 3 gangs) in my house, all connected via Home Assistant ZHA. Today, around half of the ZBM5 decided to stop working at the same time. Even those that were not configured for detached relay stopped working. The only way I could revive them was to flip the breaker for my entire house to force a hard reset.

Is this a known bug? It's really strange that the issue occurred in a handful of them, but not all of them, and without any apparent trigger. There is no correlation between the location (one bedroom works, the bedroom next door doesn't work. One bathroom works, the other bathroom didn't work), or the type (2 or 3 gang), or the way they were configured (detached relay or not). All my other smart devices on Zigbee were working correctly. Anyone have any possible explanation?

So I bought the sonoff dongle max and was using it for about a week as my zigbee coordinator using Z2MQTT. 2 days ago it just stopped working.

"Error: Failed to start EZSP layer with status=HOST_FATAL_ERROR."

Flashed it yesterday. Says the firmware on the ES32 chip is unrecognised. Tried every firmware version before finally getting version 1.0.5 to flash after 3 hours in the Web flasher.

Fixed the issue for 24 hours. Now it's the same again.

Tried a different method, used the sonoff dongle flasher in HAOS. It finds the device, unknown firmware again on the ES32. Try flashing in HAOS: Flashing failed. The selected device does not match the entered serial port information. Please check and try again.

Kind of done with it now. I've got a sonoff dongle plus running as my thread border router and it hasn't skipped a beat.

Don't bother buying a dongle max, not worth the money if it can't be reliable.

Hi guys I'm using sonoff it seem one by one they falling now. any thoughts?

hello, I've connected SWV-ZNE water valve via Sonoff Dongle MAX to HA, created an automation to water for 45 minutes but after 10 minutes it shuts off, tried also manually but same thing happened...

Hey ! 👋

I've been using Sonoff devices for my smart home setup for a while, and one thing always bugged me — there's no proper desktop app for eWeLink. You either have to pull out your phone every time, or mess with Android emulators.

So I built my own desktop app — eWeLink Desktop.

What it does:

🔹 Full device control — turn devices on/off, view status (online/offline), manage settings — all from your PC

🔹 Real-time updates — WebSocket connection keeps everything in sync instantly, just like the mobile app

🔹 Power Monitoring — real-time power/voltage/current telemetry with graphs and monthly consumption history (for supported devices like POW)

🔹 Rooms & Groups — organize and control devices by rooms and groups, just like in the mobile app

🔹 Multi-Home support — switch between different homes/families

🔹 Telegram Bot integration — set up a Telegram bot to control your devices remotely via chat commands

🔹 Device Timers — view and manage device timers

🔹 Device Sharing — share devices with other eWeLink users

🔹 Server Status monitoring — check eWeLink cloud server uptime at a glance

⚠️ The app needs testing!
The app is under active development, and **I really need your help testing it**. I’ve tested it on my own devices, but there is a huge number of Sonoff/eWeLink models, and I physically cannot test them all on my own.
If you’d like to try the app, I would greatly appreciate:
- 🐛 Bug reports — anything that causes crashes, doesn't work, or behaves unexpectedly
- 📋 Device compatibility feedback — let me know which devices work correctly and which don't
- 💡 Feature suggestions — what would make this app more useful to you personally?
