Hello,
I’ve managed to create a second SDA and SLA connection using some code in the CLI that added a second bus on the GPIO pins for multiple sensors and it’s showing up in terminal “sudo i2cdetect -y” search but when I look to add the sensor in Openplotter i2c app, it doesn’t show up so I take it that OP only listens to one single bus and you have to wire multiple sensors in parallel?

Good to know, thanks Jim! Now the next question is what if I have two identical INA260 sensors, that I'm still trying to figure out how to get in OP, one for house and one for starting Batts. They seem to be registered in the i2C protocol as having address 40.
assign a different address to one of the boards
soldering the A0 pad of the board you set his address to: 0x41
soldering the A1 pad of the board you assign the address to: 0x44

Well, I guess if I RTFM'd the damm board I would've known that! My apologies. Now, bigger question, have you been successful in setting these INA's up in OP? IE: what are the actual sentences in i2C etc...
no i haven't messed with the software for over a year. there should be no problem setting them up thought, many people have been successful with it.
Hello there,
INA260 should work? I tested today, default 0x40 address, near a BME280 at 0x76.
The BME280 is working nice but no signal from INA260, even it's address is detected
Any advice for debug it?
