@teastain2 Bingo! that worked, changing
Wire.begin();
to
Wire.begin(26, 14);

so pinout for I2C on T-relay 8X is
SDA: pin 26
SCL: pin 14

thank you!

@teastain @rogeriocpe any progress?
I'm using T-relay 8X and would like to use INA219 too,
somewhere I've found I could use pins 32 and 33 but they are used by relays, so what?

I also tried to scan with common I2C scanner code, after connecting to pin 14 and 25, without success, no device found.
