Is that a TH 16 ? I have the 10 and the only thing I can see using a magnifier is the bottom left of this picture showing vcc j3 ground.
Thank you Scott !!!
does this work with sonoff 4ch pro?
do I have to solder headers to the device?
thanks

HI all, to connect the FTDI adapter to the Sonoff, do you need to solder on a 5 way GPIO pin to the Sonoff, then connect the FTDI to the Sonoff’s new pins via Female to female dupont wires?
Hey guys, just bought 8 POW units which arrived today.
I followed instructions from https://www.youtube.com/watch?v=FxV_zWvxbSE and replaced the firmware.
I have connected the device to my wireless network and into smart things.
Problem i’ve enchanted is every 13 seconds it turns on then 13 seconds later off, and continues over and over.
Have i used an incorrect firmware for the 16A POW version, or do they all share the same firmware?
Has anyone else experienced this before?
Cheers
I uploaded the TH firmware now it seems stable and not on/off every 13 seconds; I still have no energy monitoring capability so suspect there must be a POW firmware somewhere but i can’t find it in this thread?
Mmmm, i managed to find the POW version in https://github.com/erocm123/SmartThingsPublic/tree/master/devicetypes/erocm123/sonoff-pow-wifi-switch.src however after doing the firmware upgrade via the web interface it rebooted but i can’t load the WEB interface anymore though i can ping the device.
I tried doing another flash of the device directly with the POW software which appeared to be successful
in the windows CLI, however on plugging it in it appears to have saved the wifi details etc and just reconnected to my wifi; so the flash didn’t wipe the old settings?
Any help would be appreciated
Sorry for all the spam; incase anyone else needs to know (hoping it helps someone), hold down the button for 15+ seconds and resets wifi, all fixed 
I flashed the s20 successfully, but not s20 wont even start/blink when i connect to main. Any solution for this?

Hi,
I’m having the same issues as you. I would like to use CoRE as well to issue a refresh like you are doing, but unsure on what your settings are like. Can you let me know what your if / then settings are?
Thanks!
I have attempted to flash the Sonoff Basic but have encountered an issue.
I flashed via the ESPEasy method as outlined in the first post. I connected my Adaptor to my Board and put the board in pairing mode and the flashing took place successfully based on the screen results. But I don’t ever get a Sonoff wifi broadcast.
I’ve attempt the flashing about 5 times and it flashes ok, but same result. I can confirm my cable were good as I tried loose ones during different tests and as expected the flash did not connect.
One thing I have noticed is that the led no longer flashes on the device (it never flashed since the first initial flash!!!)
Anything else I can try?
Thanks
Update - just found this post Are there one or two types of Sonoff Basic? , I have the updated model, therefore it seems i should flash the alternative method.
Yeah try using NodeMcu the instructions are now pinned to the first post.
And then if still no WiFi after flashing reset the WiFi and it should show then.
is there a way to put it in developer mode if you’ve broken the button?
@Steveuk23 - yep that did the trick. Thank you for confirming. I wasn’t sure if/when that approach was the right one to take and I wasn’t sure if I had thrashed the device by mistake.
Is there any recommended settings to set configure in the admin part?

Not really leave most default.
You can select the boot option so what to do after a power cut wether you want the switch to turn straight on or off.
