A rain sensor just tells you if it’s raining or not. A rain gauge will give you cumulative rainfall values. I know there are DIY projects to make HA-compatible gauges but I’d rather have something out of the box, at least in terms of hardware.

I found this on Amazon, and it appears to be be a clone of a more expensive station by Ambient Weather. It looks like it could be made to work with HA as it has a web interface, but I’m not sure if an app is required for setup. The rain gauge also doesn’t seem super accurate, which is frustrating as that’s the only thing I really care about.

    I also have an ecowitt weather station, bought a separate GW1000 receiver which feeds into weewx (completely local) and home assistant. You can also add in up to 8 extra temp and humidity sensors so I have some of those in different rooms and the green house.

    The rain measurement is a tipping seesaw type so strong winds can sometimes cause inaccurate results

    Has usb connector too

      I have the Ecowitt WS90 with a gw2000 hub which has been solid since I installed it Mid July of this year:

      Displays Daily Rainfall, Rain Rait Per hours, Week to date Totals, Rain State and the totals so far.

      This is from Home Assistant and (Yes it says the rain state is WET It’s either that or dry, a very binary state on the sensor) I live in the PNW where it mostly rains this time of year so the totals are pretty accurate. It uses a Rain Piezo which works by converting the mechanical vibrations caused by raindrops hitting its surface into electrical signals. This process allows the sensor to detect rainfall. I’ve been toying with the idea of getting a manual rain gauge to confirm the totals, but I’m happy with it so far though!

        I ended up going with this one. I can’t confirm the accuracy of the gauge as it hasn’t rained much yet and I don’t have an analog gauge to compare, but I suppose it will work fine as a rough estimator if it isn’t accurate.

        There’s no app or account required which is the biggest selling point for me.

    I have a weather flow tempest. Expensive and my first one died after a few years but it works well and gives you cumulative rain readings through its native ha integration.

        There is both a local and online integration available. Some of the sensors like the weather forecast (which is the most accurate weather forecast I have ever had for my location) are only available from the cloud, others are available locally.
