I purchased my first 4ch Pro (R2) on amazon. I'm attempting to flash Tasmota to integrate with Domoticz to control my door strikes. This will replace my old X10 relays. I think that I have everything figured out, except my 4ch Pro (R2) does not match any online pictures, so I'm not sure where GPIO0 is located. Unlike all of the online pictures, where the board reads, "sonoff_4ch_pro V1.1 2017-4-26", my board reads "sonoff_4ch_pro V1.0 2017-11-10." I also have a long bar for my 433mhz antenna, not the black coil of wire. The ESP8285 is also soldered directly to the board, it's not on the little riser board. Is this just because I have the R2 model? Can I just locate GPIO0 on the chip specs and continue?
