Python plugin: Xiaomi Mi Flower Mate
Posted: Tuesday 20 February 2018 16:15
by blauwebuis
With this plugin you can easily connect to your Xiaomi Flower Mate devices.
These are Bluetooth LE plant monitoring devices which cost about 12 dollars. They last up to a year on a coincell battery, and measure moisture, temperature, light and conductivity.
https://wiki.hackerspace.pl/projects:xiaomi-flora
1. Install the plugin
2. Keep automatic mode, or change to manual mode. In manual mode you can control which devices should be enabled, simply by adding their mac addresses on the hardware page.
3. The plugin creates 4 sensors (moisture, etc) for each device.
4. The plugin creates a special switch. Toggle the switch to get fresh data from all sensors.
By having a switch to poll for new data, it becomes easy to create timers and other fun integrations in scripts.

Great to see new development! Are there any advantages above the original wiki script?

UPDATE
I've added an "automatic" mode. It does a bluetooth scan when Domoticz starts and then automatically adds any new MiFlora sensors it finds. So after installing this plugin your MiFlora devices will automatically show up.
Advantages of using the plugin:
- Much easier to install than the old script.
- No need to manually edit anything in the script. The plugin even has an 'automatic' mode.
- Easy to change polling frequency: just set a timer for the 'master switch' which the plugin creates. Goodbye cron!
- Curious how your plants are doing right now? Just toggle that switch.
- It uses the new BluePy library, and the latest version of the MiFlora library, making it more robust.
The Mi Flora / Mi Flower Mate devices have come down in price a bit too ( $12 ).

Is it possible (how) to poll, let say every hour instead once a day (grafana)? As I noticed it checks the status of both on and off.

Setting a timer is easy. Just setup the switch with a timer as you would any other switch.
I could make it so that the switch immediately turns itself off again.

after that, switch doesn't respond and no new data from sensors, only solution is restarting domoticz.

@idanit: you are using a older version that still has debugging output enabled.
@Oliwier: how many Flower Mates do you have? I have tested it with 2. I also got the error you mentioned, but fixed that by adding a bit more time between readings of all the sensors. Perhaps if you have more than 2 it needs a bit more time still. Or perhaps you're also using the older version, as you also get the debug output.
You can try making this longer in the code too:
Code: Select all
# give bluetooth a little breathing room
time.sleep(1)

I've noticed that it is 1.0.0 version, but I just git clone it from Your github. I did it again but it is still 1.0.0.
I am not much of a python programmer, should I change it to

?

1. I got 5 MiFloras
2. I've changed sleep time to 3 sec.
3. I git clone plugin onece again... no 'onHeartbeat' but same as @Idanit plugin v 1.0.0
4. still got the same error as before:

I've read somewhere that there are some issues with python 3.5 on Raspbian Stretch.
I uninstalled version 3.5 and installed 3.4, but the problem remained. Also 10s did not solve the problem.

UPDATE
I've uploaded a new version of the plugin that may fix the bluetooth issue.
The plugin now uses the heartbeat function to poll one sensor per heartbeat.
- This could give more space between polls, and thus prevent the Bluepy helper from crashing if users have a lot of Flower Mates.
- This also keeps Domoticz happy, as the plugin now doesn't take up too much processing time.
The plugin now also toggles the switch visually to "on" when the switch it pressed, and turns itself visually back into the off-state once all the polling is done.

I'm also facing the BTLEException error. 90% of the time the plug-in is working great, but it seems when the script has trouble seeing the Flower Mate the script crashes and i have to restart Domoticz before the script will work again.

That a really good Job guy !
I'm using BLE Scanner Plugin too, I have 2 bluetooth LE dongle, can you add a choice of which one to use please ? using dongle mac adresse is a good choice, hci0 or hci1 can be good too
Actually, if i check miflora info running blescanner this give this :
