Integrating SEN0575 Rainfall Sensor (I2C) with ESPHome / ESP32

Hi everyone,

 

I'm working on a weather station project using an ESP32 programmed with ESPHome and I'm trying to integrate the Digital Rainfall Sensor (SEN0575). The sensor seems to use the I2C interface only. I'm having trouble getting this sensor working within ESPHome because there doesn't seem to be a built-in component for the SEN0575's I2C communication. I've searched for external components or examples, but haven't found a clear solution yet.

 

My question is: Has anyone successfully integrated the SEN0575 (using its I2C interface) with ESPHome? 

 

If so, I'd be grateful for any advice:

Is there a specific ESPHome external component or Arduino library I should be using? (If a library, where can I find the source, e.g., on GitHub?)Could you share any relevant parts of your ESPHome *.yaml configuration (especially any lambda code used in a custom component)?Are there any specific setup steps or known issues when using this sensor with ESPHome/ESP32 via I2C?

I've already confirmed my I2C bus is working with other sensors (like a BMP280). I just need help figuring out how to talk to the SEN0575 specifically.

Thanks in advance for any help or pointers!

 

Best regards,

Alex
