Droplet: Smart Home Water Sensor

I checked the Droplet for over a week against my water utility's meter. Daily totals in the app landed within 1–2% every day, and the hourly chart clearly picks out showers, laundry and dishwasher runs. Excellent for a clamp-on with no plumbing work, and install was easy. The downside is integration. Droplet advertises Home Assistant support, but the official integration never connected. "Regenerate code" kept returning the same pairing code, and I wasted a lot of time on it. MQTT works, but its volume data adds up to 10–20% more per day than the app shows. Great sensor, and I'd buy it again. If the integrations matched the hardware, it'd be an easy 5 stars.

I purchased this to replace my old rachio flow Sensor. I am out of town often and use the flow Sensor to ensure my sprinklers are working well and therenare no leaks. I had a difficult time getting the sensor to connect, primarily due to paint being applied to the PVC many years ago. After sanding away the paint the Droplet connected and has worked well.

I like that it tracks water usage in general. But i was hoping it would be more accurate. It's not accurate as to which source is used - many times it confuses kitchen faucet or bathroom faucet with dishwasher or washing machine. other times it confuses faucet and toilet or irrigation. I wish it would be more accurate so it can give me better metrics as to which source is used the most or least.
