Dead sockets??

[Phil]

A bit of trouble with a gas cooker ignition circuit coinciding with me in the electrical cupboard when the main mcb tripped - me thinking i had elbowed it or something switched it up and held it on a second or two while the cooker fault pulsed it off repeatedly...

The resulting rapid cycling on/off of the main power did a number on a few tasmota devices, One set seemed to auto-recover after a few days.

However the koogeek sockets  aka KLUP1, remain dead so far. Perhaps im a bit dim and the gpio table in the link simply indicates the module pinouts are unknown/undocumented as yet and im flogging a proverbial dead horse

Opening up reveals an esp8266 daughter board secured perpendicular to the mains pcb with soldered connections.  there are no pin out identification screen prints on the esp pcb indicating gpio  however there is a blue led lit which is not evident when closed up as the indicating rgb led remains OFF- so some power is getting to the esp??

But with no indication of which if any connections are the RX and TX lines or gpio-0 i cant see any way atm to reflash these..  iirc originally they were flashed via a raspberry pi-0 and a  tuya convert procedure iirc..   

Am i missing something Glaringly obvious (it feels like i am..) - any help will be much appreciated.

Doesn't tasmota, and other devices, use rapid boot count to do a factory reset? They assume if it cycles 10 times in 10 seconds or less each, config must be bad or deadlock, and do factory reset.

I think there is even a setoption to disable it

Other brands on other types of devices even, have similar methods. I remember a DECT repeater that would reset after a rapid power cycle, very annoying

Cheers, indeed yes with tasmota its 7x on/off cycles within a few seconds iirc, It should discard wifi settings and start the hosting of the access point to enable reconfiguring.  I had to employ this method to connect to a sonoff bz?? led ceiling plate once upon a time. and it was a pita.  

I have checked for any unexpected access points appearing when plugging in the devices to test every few months or so.  I have not considered any 'legacy firmware responses tho? - how would that work with a f/w flash to tasmota?

The esp module itself appears to be a small square castellated module its top entirely capped circa 14mmx 12mm with 6x6x6?x2 connections solderpoints..  not matching any modules listed in the esp8266 wiki  (guessing at the 6x connections on the side connecting to the main board as i can see some connections but i cant count then reliably due to obstructions so am employing a guess at symmetry?)

It's worth trying unplugging the device for at least 5 minutes then holding the button for 40 seconds after plugging it back in. Most of the ESP8266 devices had  24 connections (8 connections either side and 6 on the bottom - ESP12-E for example) but the ESP8266-WROOM had 18 connections in total (2 x 9)
