Getting Started with Sonoff 4CH V2.0

#1 Post by rcampbellbassac » 20 Aug 2019, 15:06

Hi!

I'm looking for general recommendations on getting started with ESPEasy on the Sonoff 4CH V2.0.

The current factory firmware is PSF-A04-GL. The chip is labeled PSF-A. I'm not finding a lot of information on how to identify the correct firmware for this chip and would appreciate any pointers or recommendations.

I have ESPEasy installed. I am using a USB to TTL Serial (https://www.amazon.com/gp/product/B00QT ... UTF8&psc=1) Since it's power is 5v, I'm using a separate power supply to supply the correct voltage to the board. Running Windows 10. Haven't yet gotten anything meaningful out of the serial connection (output is unreadable at this point). Should I? Is there a way I can confirm that it will work before I attempt to upload the firmware? The device works when connected with the eWeLink app.

Linked are some photos of the device.

PSF-A is ESP8285 - use firmware for this version

Putting board to download mode - look at 1:16 here:

I recommend esptool for flashing ESPeasy .bin file.
