I just installed Openplotter on a new computer and got the same message in the status bar of the I2C app. As a result I cannot add my sensors.
Hardware:
I2C seems to be working, sensor is shown at address 76
Software:
Installed from image 2022-07-18-OpenPlotter-v3-Starting-stable-64bit-img
Available updates installed.
I2C Sensors 3.3.7-stable
GPIO 3.1.0-alpha
/boot/config.txt excerpt:
Hardware:
- Raspberry Pi Compute Module 4 Wireless / 8 GB RAM / 32 GB eMMC
- Waveshare CM4-IO-BASE-B baseboard rev. 4
- Waveshare 8inch DSI touch display
- BMP280 sensor
I2C seems to be working, sensor is shown at address 76
