I have recently had the 3 way sonoff touch light switch installed and all works fine , apart from the linking to the app or smartthings - neither will work
when I go to pair mode it just says connecting and does nothing
I think it has something to do with the wifi conection - i have a bt whole home mesh network in my house which runs on 2 + 5 ghz frequencies - no way to turn off 5ghz
so any ideas how to get this to connect to the smart hub so i can alexa control it
this is the item i have installed -
Since it’s WiFi, smartthings won’t see it (even if it joins your network - sounds like it isn’t joining) but you can use ifttt, ewelink and virtual switches to eventually get it working
Which BT hub do you have ? The hub 6 lets you split 2.4Ghz and 5Ghz (and then turn off the latter) once it’s joined and ewelink can see it, then you can turn 5Ghz on and merge them back
There is custom firmware available that allow you to see local changes on your sonoff on ST.
2017_10_04 Update: If the flashing method in this first post does not work for your device, try the method mentioned in this post:
2017_05_10 Update: Sonoff Dual - Firmware and device handler and child device handler. Flashing info here. Sonoff 4CH - Firmware and device handler and child device handler.
2017_01_21 Update: Release of firmware and SmartApp updates for the Sonoff Touch and Sonoff S20. Picture for flashing Sonoff Touch in this post.
2016_10_14 Update: I have been playing with the Sonoff TH (16 Amp Version) and am finished with a SmartThings capable firmware for it. This device has a 10 & 16 Amp version and support for a temperature sensor attachment. The device handler supports both temperature and humidity. Here is the firmware & here is the device handler. Y…
There’s a newer version of this that is based on Tasmota. Just gotta read down through the tread.
unsure which bt hub - and im not using it anyway - im using bt whole home wifi - the mesh network
is this actually required to get it to work in ST - I thought it was available without having to flash
all I am looking to do is get it seen in Alexa via ST so i can tell it turn the lights on or off - is this not possible without flashing - as it doesnt look reliable after reading some of the comments
AFAIK, even the mesh disc still need a hub of somesort. Which box connects to your phone line ?
i have a virgin hub connected to the mesh - a problem with it is the switch is 1 side of the house and the hub is the other
I see. I still think you need to have a 2.4Ghz only network for the initial join. and I don’t believe flashing Tasmota (I’ve not used it) will help as the switch is based on ESP8266 module which only does 2.4)
ok that might be a problem ill see if i can find an old router and see if it can be connected to it - i read somewhere i would have to set the old router SSID to the same as the network i want to connect it to - get it connected and then turn old router off and then it should reconnect to the network i require - does old router need to be connected to an IP
Yes, the old router would need to be able to connect to the internet to get the light switch registered with the server that ewelink uses. You might be able to use a phone in hotspot mode too.
I tried phone as a hot spot as well - but believe the phone is not using a 2.4ghz connection - got the same message when i tried to set it up anyways
If you want local control over the device that does not rely on Alexa, then you have to flash it. If you are willing to not be able to control it if Alexa is down, then you can use Alexa.
I have the same switch and would like to flash it so ST will see it.
Can someone tell me if this if possible wirelessly or do I need special cables and software to do this?
I’d like some sort of idiot guide if possible!
You cannot flash it wirelessly. This device doesn’t have the Sonoff DIY mode.
