Hi - anyone ever flash this device? The chip inside is 9 pins a side (18 total) with an wire for an external antenna. Otherwise I have no indications what kind of chip so hard to tell how to flash this with firmware.
First time flashing a device…
As you can tell by searching, no one has mentioned those devices on this forum.
Can you post some info. A picture?
Did some more research and under the covers is an Eco Plus from Kab Enterprises. Once I figured that out there were a few hints how to flash. My problem was I tried to solder wires onto the esp chip and I shorted the Vcc. So the device is toast. I saw some people make jigs to flash commercial devices and that would have been better choice.
I’m gonna just use a Shelly 1 connected to the relays I harvested. I was hoping to reuse the nice neat box for 80 bucks. But lesson learned - gotta be super careful soldering around an existing board.
I was successfully able to flash my Dewenwils switch with Both ESPHome and Tasmota. I just created a write up on ESPHome seen here and also the Tasomta flash from here worked perfectly as well. I will be creating a couple other write ups on ESPHome for other branded ECO-Plugs later this week.

Could you share the pinout, the chip on the esphome doc from [ryansmigley],doesn’t ressemble this one… I’d like avoiding bricking it!
