This is interesting. Thanks for the link. I am using sonoff dual/ basic for single pole switches and Kasa smart switch for 3 way or 4 way. Sonoff mini will get in right in the middle for 3-way switches. For single pole i modified the decora to act like a momentary switch but it is not consistently working. Let me try Mini and see if it works well.
Thank you for the link to 4CH device handler and smartapp. I flashed your bin file on the Sonoff, since with the newest tasmota SW I could not find it, when using discover in app. But after flashing your firmware, I was asked for Wifi password, which I could not find. I just reset the Sonoff and then I was not prompted for password. Now I got it working in Smartthings. Maybe you should add password, so others can install easier 
Works great!!
The wifi password is in the first post.

Connect to Your Home Wifi
Now, plug the switch into power and wait for a moment. It should create an access point named Sonoff.[macAddressofSwitch]. Connect to that access point with the password: configme and it should redirect you to the page where you can connect it to your access point. If it doesnât redirect you the IP address is 192.168.4.1. Put in your network access point information and hit connect.
The switch should then connect to your Wifi access point.
password: configme
I am using the Sonoff TH16 for my pool temperature. Is there a way to connect a display to it to show the water temperature?

Tried this, but it did not work. Maybe another password for the 4CH bin file? But it does not matter ,since I just cleared the Sonoff so now no password.
Got a strange problem. I just got a sonoff basic r2 ver2. it Flashed fine. Assigned my network and itâs not getting an IP address. I check and it does get an IP for a few seconds then drops off the net. Switch button controls device correctly.
Should I re Flash and try again?
Oh and I have a 4ch pro that works just fine with my wifi. Do the devices share same wireless chip/software?
Which file is the actual for the Node Flasher? The link to Github brings up numerous files. I cannot seem to find which one will open the flasher tool.
Strange, I havenât seen that before. Maybe try a reflash. Try connecting it to a different access point just to rule that out. You could also reboot the router.

The first post references the below which has a link to the flasher and some better information about flashing:
I set this whole thing up last month and changed assigned a new password to it. I changed my wifi password on my router today and needed to change it on the Sonoff. I unplugged the Sonoff and plugged it back in, and it started broadcasting itâs own SSID again (âSonoffâ+MAC address). I joined itâs network and when it asked for the password it wouldnât accept the one that I had created for it last month. It took âconfigmeâ. This concerns me, because it means if the power goes out and comes back on, and the Sonoff canât immediate reconnect to my wifi, anyone can change the Sonoffâs wifi configuration and make it connect to their own network, since âconfigmeâ is known to be the default password.
Has anyone tried this on the new Sonoff mini yet? It looks like the perfect device for adding the 13 light switches left in my house to Smartthings without breaking the bank.

The password is currently for control of the device & configuration. The wifi password is statically set at configme. The device tries to connect to wifi every few minutes, so if the power goes out it will shortly connect back to the access point.
Technically, if someone connected to it during that short window, they could attach it to another wifi network, but wouldnât be able to control it or configure it.
That being said, it wouldnât be too hard to change it have a configurable AP password. I will try to update it when I get a chance, but if anyone else wants to, that would be great.
To use the 1 Sonoff mini to control a 3-way switch setup you need the line and the load in the same gang box (see the diagram on the Sonoff mini page). Both my 3-way switches have the line in one box and the load in the other. One hack to fix this with 2 Sonoff minis would be to use the 2 traveler wires to sent power and neutral to the box with the load. Hook that switch up as a single pole. Hook the second Sonoff up without anything connected to the relay, and sync the two Sonoffs through Smartthings.
General Question , but I cannot get the Auto Off to work. In Smartthings it says succesfully saved.
Any ideas what to try?
And a second QâŚ
Is it possible to connect (and read) dht11/22 on a Sonoff Basic R2 V1 (the newer ones without the 5th pin , gpio14, I think?) I know there is a Sonoff TH.
Thanks.
Hi I have a th16 which I can control via smartthings however Iâm not getting any temperature or humidity readings I am using the am2301 sensor which if I put tasmota firmware on the th16 I receive readings on the web interface. Any ideas what could be the problem
Hi, Does anyone has been able to make it work the inching option of the 4Ch relay with Smartthings using the custom fw and device handler ??
I´m pretty newbie on this but couldnât get it work with the info I´ve found.
I´ve successfully added the 4 relays as ânormalâ switches on ST (but configured as inching in with the pin setup at the board). When I try to change the status from the ST app I´m only able to activate each switch once, and then it gets hung (I think it´s related to the inching option, but couldnât found how to properly configure it within ST). Is there any way to make it work ? Any help or advice will be appreciated
Thanks !!
Make sense. Did you flash mini with Ericâs firmware? Or you are using eW link app?
Hi Eric
I flashed a POW R2 with your firmware and had no issue to add it to Smartthings with your connect app.
Iâm however not getting any V, W or A readings in Smartthings. (All readings are 0).
I donât see any errors in the IDE log:
The web interface also shows no readings:
(The switch is connected to a pool pump rated at 1500W.)
Iâve tried obvious thinks like rebooting but that made no difference. Unfortunately I flashed the firmware on receipt, not checking if the device report any readings, so it could be that the device is faulty.
Have you perhaps encountered this and do you have any suggestions?
To Eric - thanks again for all this. Just setup my first Sonoff SV as a garage door opener works great using the Rboys app. But, I have been unable to get the configure button to work on ANY of my 5 sonoff devices several of which have been running for months. For the garage relay, I want to set the auto-off time but it wonât let me. Any solution to the orange dot / inability to configure with the flashed firmware? I did not find it using search on here sorry if I missed it.
Erik,
A new Sonoff module had just released. Any Chance for a DH? The device is SONOFF T4EU1C and its main advantage that no neutral wire required !! You can find more details here :

Bought one direct from China, problem iâm having is that the wifi chip is the same as the touch, but the board is radically different, and no idea where GPI0 is to get into programing mode. ITEAD told me its not flashable, but they would wouldnât they.
