There already are some discussions on this forum about this particular water meter, for instance:

TUF-2000M Ultrasonic Water Flowmeter MODBUS integration

UPDATE: Resolution below I cannot integrate this flow meter into ESPhome via MODBUS. The flow meter is TUF-2000M on aliexpress or Amazon. Everything is hooked up correctly to my ESP8266. I followed the instructions here: Using the ESP8266 Arduino code in that blog, I can read various registers such as the Flow, temperature inlet, etc. The TUF-2000M MODBUS registers are here on page 39: https://images-na.ssl-images-amazon.com/images/I/91CvZHsNYBL.pdf. However, when I try to integrate into ES…
