Domoticz just for flower power devices?

[gillesMa]

Hello,

I have several flower power devices and pots, but Parrot, the manufacturer, has just decided to shut down its cloud servers. The devices have become useless as is.
My idea is to use Domoticz just to connect to these devices. Hence my requirements are rather minimal: if I understand things well, I only need to have a working bluetooth sensor on the host with Domoticz, and install the flower power plugin. What would be the easiest and cheapest way to achieve that?

I have thought about buying a Raspberry pi zero W, that seems to fit the bill. Would it be fine for running Domoticz in my special case?

Alternatively, my computer is a NUC with a bluetooth device. Would it be possible to use domoticz in a docker container, and detect bluetooth devices? I've tried to go this way so far. The container works well, but I don't know how to identify the bluetooth device inside the container (and I don't know if it's possible).

Thank you for your help.

Hello,

i'm trying to use Python plugin parrot_flower_plugin with Domoticz Version: 2021.1 on Raspberry Pi 4B but I got this error message in domoticz log file.

I installed the prerequisite as mentioned in Git : https://github.com/tazounet/parrot_flower_plugin
What could be the issue ?

[waltervl]

Give the plugin.py file execute permissions. Right click on the file to change its permissions, or use the terminal to navigate to the directory, and then type: sudo chmod +x plugin.py

You could try to use sudo to install the libraries:
sudo pip3 install bluepy
sudo pip3 install btlewrap

[waltervl]

on your RPi in a terminal window go to the plugin directory and run
sudo python demo.py

Then you should get some more information if the library is working.

Else make an issue on the plugin GitHub. Perhaps the plugin owner knows the solution.

I replaced it with this one that works fine : https://www.domoticz.com/wiki/Plugins/Mi_flower_mate

Yes, that is also a possibility

Added these above icons in a new version (plus correction of conductivity device unit) in https://github.com/flatsiedatsie/Mi_Flower_mate_plugin

This plugin works with all sensors that have 'flower mate' or 'flower care' in there name (when bluetooth scanned, or that have C4:7C:8D: in BT mac address prefix), thus not only Xiaomi sensors.
