@Panos - Ive achieved this by using the workaround FAQ: Can I trigger an Echo Action without Speaking to It?
I dont have alexa speakers but utilised the Alexa app - plugs working again! Hope this helps.

I am based in the UK and all my sonoff classic devices stopped responding on Tuesday.
I have 6 or 7 devices and none of them are now responding.
Everything else is fine,
I am not sure if there was an update or even where to troubleshoot this.
Any ideas?
Hi @erocm1231 - I love using your Sonoff firmware and smartapp, thanks. Reliability was never an issue but I switched to the new ST app a few weeks ago and since then Iām struggling with "Device Offlineā quite regularly. Also, each time my home router (where my DHCP pool sits) reboots, I have to restart all the sonoff switches, which isnāt so easy to do with some of them. Is it possible samsung has introduced issues with the new app?
Some of my Sonoff switches show the wrong IP in Smartthings (and thus donāt work) vs my router but I canāt get them to update.

Not sure what is going on but when your router reboots they should reconnect. At least mine have for years without issue. Also, the SmartApp is supposed to handle ip address changes which seems like what may be causing the problem with offline devices. Anything different going on with your router?
Check the logs for the Sonoff Connect app and see if SSDP reports are coming in that would update the IP address. If they arenāt there might be something going on with your network and SSDP.
Does this DH work for the Sonoff Basic R3?
Iāve been using the 4Ch DH controlling a T1 2 gang switch and it was working fine until I had to migrate to the new ST appā¦ now the switches have disappeared from my devices in the app and in webcore. My simple Sonoff switches seem to be fine. Any ideas?
Me too, Same for the 4ch wifi switch. Now only sees parent device and google home has also lost visibility through bridge, New app is becoming a pain.
Does device discovery really take more than 5 min? I donāt ever remember it taking this long! Got a new mesh router and had everything working. Rebooted, then couldnāt get the sonoff to respond. Deleted it by mistake and now Iām unable to add it again!
Gonna reply to myself so I remember how to fix this next time. Once its connected to network, reboot/unplug, then try doing device discovery in the app. Once its discovered and set up, you need to hit the refresh button in the CLASSIC APP! Then temperature will start displaying again. I guess someday this will eventually be totally broken when the classic app is completely gone? I only use this for the temp probe, so probably only my specific use.
Another issue with the terrible new app. Old one is soon I am afraid. I am looking into home assistant. Thinking of chopping smartthings for good. Anyone think HA any good? I loved smartthings but seems Samsung are done with it as they really dont care about the user.
Same brother, I have been looking into this but they require us to purchase their MCs -
If you find something else, do let me know!
Hi @erocm1231 - a v. quick question - Iām (painfully) going through my forced migration to the new app. I have six Sonoff 4Ch devices.
Iāve update the device handler, and deleted the children, but I couldnāt get the children to re-create.
If I completely deleted the master device and then re-added it, then it worked - do I really have to do this for all of them?
Also, my sonoff TH doesnāt even show in the new app - do I need to remove and re-add that?
(I realise this is totally out of your control, but some guidance would be great!)
The new app might be good if I can make everything work, but itās annoying that they didnāt keep backward compatibility, and that theyāve forced me to use the new app, even though the old app still works for my needs.
Thanks for all your work creating these and continuing to support them!
Best,
James
You have to update the device handler, delete all the child devices, and then have them recreated with the new device handler installed. You can do this by changing a preference in the device settings and then changing it back.
@jamesxheath Maybe you are missing that last step of changing a preference in the device settings and then changing it back.

Thanks a millions Eric, I will give that a shot. Appreciate all you work on these. Using your info for years 
No luck Eric. I could not rediscover using Sonoff connect smartapp, smart app is giving error when trying to save. I forget all my steps its been working so solid for so long. The new app is terrible for my esp temp sensors too. I think I am going to move. I use mostly my own Pi based system for heating and can control sonoffs via http and MQTT so might look into making that remote. Smartthings offered me remote access you see, Think I will knock it on the head, they must not care about users.
Actually, you only needed to delete the child devices and not the parent device. To solve your new issue you will have to look at the logs when you try to save the new device.
Did you ever get this going? I have an old TH16 with the DS18B20 probe running for years but the one I just got with an AM2301 is not giving me any temp or humidity readings. Iāve removed and readdedā¦reset wifi on TH16ā¦everything short of reflashing.

I just updated the DH, deleted the child devices and then changed the device name in the Sonoff App for the 4ch device and it all started working again. Thanks @erocm1231 ā¦I thought I was going to have to install the Tasmota firmware to get it working again.
ā¦On a slightly different topic, has anyone managed to get a switch working that isnāt close to wi-fi router/ extender? I have an outside light where I need to put the switch in the base of it - I tried a Sonoff Basic but it wouldnāt connect - itās about 15m (45ft) away and through a window and the wi-fi signal is strong enough for a good connection for my phone when standing next to the light. Iāve put an X10 switch in at the moment but would be good to find a better solution.
Hey Eric. Checked logs and figured out issue with smartapp. I had made minor change to handler name by mistake. The child devices add now but the checking status thats for a lot of stuff is showing up again. Also when click into the device the switch capability is not shown.
