WatchFlower is a plant monitoring application that reads and plots data from compatible Bluetooth sensors like Xiaomi MiJia "Flower Care" and "RoPot" or Parrot "Flower Power" and "Parrot Pot", as well as many Bluetooth thermometers! It works with international and Chinese Xiaomi devices, doesn't require an account creation, your GPS location, nor any other personal data from you!
Works on Linux, macOS, Windows, but also Android and iOS! Desktop binaries are available on the "release" page, mobile applications are on the app stores.
Virtually all phones and laptops have Bluetooth "Low Energy", but you will need to make sure your desktop computer has a Bluetooth card or dongle (and for Windows, a working driver too).
Available in Chinese (traditional and simplified), Danish, Dutch, English, French, Frisian, German, Norwegian (Bokmål and Nynorsk), Russian and Spanish!

WatchFlower has been built to be compatible with as many Bluetooth sensors as possible.
Various new Bluetooth devices and sensors can be added to WatchFlower. If you have one in mind, you can contact us and we'll see what can be done!
Checkout out this page to get more informations about the devices currently support, and get a peek at their Bluetooth APIs.
You can also create your own sensors and use them with WatchFlower! Checkout this guide to learn more about the process.
Please note that most Chinese devices have many names, usually no official manufacturer, sometimes a couple of variants potentially sold as the same base model. We do our best to identify them as clearly as we can. You can use the affiliate links below to be sure of what you are buying.

You will need a C++11 compiler and Qt 5.12+ (with Qt Charts). Qt 6+ won't be supported for a while.
For Android builds, you'll need the appropriates SDK and NDK (21+).

Using FlowerCare 'live mode' and 'historical data'
macOS and iOS
Due to a (bad) combination of factors, these platform need a patched version of Qt in order to work with FlowerCare live mode and history data.
The apps published on the app stores are using such patched version, but if you are building it yourself you can get these patches here. Without it, these two features will just be disabled.
While reading FlowerCare historical entry count, the sensors usually freeze for up to a second, and the Linux kernel consider that to be a connection timeout.
To be able to get the historical data working on Linux, you'll need to increase the "supervision timeout" value (while root):
# echo 100 > /sys/kernel/debug/bluetooth/hci0/supervision_timeout
You could also give WatchFlower binary the net_raw and net_admin capabilities, so that it could be allowed to changes the supervision timeout on its own. But at the moment that's not fully implemented.
# setcap 'cap_net_raw,cap_net_admin+eip' watchflower
