I'm not sure if it adds a lot of information, but...
- I like the work on this plugin a lot! It opens up the possibility to access the plant data, even when not in range.
- Unfortunately, I do get the exact same error message: "Error: (MiFlower) 'onHeartbeat' failed 'BTLEException'. Also, the toggle switch gets stuck, and the only option is to reset my raspberry pi.

The weird part is that it usually *does* work a few times, and I do get valid data. But after the 3rd/4th time, it crashes.

Although my knowledge on domoticz and python (especially) is rather at the very beginner level, i'd be happy to contribute to some trouble shooting here. Any thoughts about stuff I can try?

Instead of switch button why you don't use a push button to refresh?

The button already works as a push button really. It just switches back to 'off' after it has scanned all the devices.

I built the plugin, and I now also get the BTLE exception error a lot. If it crashes if it can't find the flower sensor, then we might be able to fix that. Thanks for the tip.

I think it's important to realize that (at least, for me), it *sometimes* works. This points towards certain possibilities (like, sensor is just inside/outside range), and away from other possibilities (like, privileges of the plug-in).

I can try to run the setup with my plant next to my raspberry pi. If the distance is < 1meter, I think we can safely confirm (or rule out) that that is the issue.

To be continued.

Thank you, I understand now.

"I built the plugin, and I now also get the BTLE exception error a lot. If it crashes if it can't find the flower sensor, then we might be able to fix that. Thanks for the tip."

This is my second question. One of my sensors is a little bit far away from my bluetooth receiver and sometimes it fails to read. In this case refresh button stays "on" and it's not possible to update anymore.

2018-04-16 19:51:04.991 MAIN SwitchLightInt : switchcmd=="On" || level < 0, new level:0

Please, add some more error handling and/or timeout function to the plugin.

Or is there any way to reset plugin without need to restart whole domoticz?

Thanks for developing this plugin.
Have the plugin enabled in my domoticz installation, but automatic scanning is failing. I see the following in domoticz logfile:

(Xiaomi Mi Flower) Scan failed

Any suggestions how to debug this further?

Can it be you run it as an unprivileged (non root) user? The scanner needs to run as root the script says.

I am not aware of a way to make the plugin run as another user and only the sub module run as root. I think it is not possible due to security constraints (or am I mistaken?)
Guess you can then only use the manual configured mac addresses you found with "hcitool lescan".

Hello,

First of all thanks a lot for this cool plugin :)
I confirm the behavior explained by @bartS12, at around 5 meter of my raspberry, i can't get the data from the sensor but if i move it near to the raspberry (arround 50cm) it's working well.

Are you looking for an update ? :D
Thanks

Hello,

I always get this error:

This is on a Rasp3. Bluetooth from raspbian discovers the Mi Flora device, so I supose that Domoticz should discover it too.
I have tested with manual or automatic, with no luck.
When button is pressed turns virtual switch off, and get then the error.

Someone?

Nothing, no reads after 24 hours. I wonder if the Mi Flower must be added to raspbian devices, associated, or it is no needed.

I have read that it is required to "You'll also have to give Python to access Bluetooth trough additional libraries you will need to install.", as said at https://www.domoticz.com/wiki/Mi_Flora_Bluetooth_LE
Not sure what to do or if it not necessary with this method: https://www.domoticz.com/wiki/Plugins/Mi_flower_mate

Thanks

Any news on solving the Error: (Mi Flora) 'onHeartbeat' failed 'BTLEException'. Running Pi 3b+ with 11 mi flora sensors :roll:

After a long a work (and a bit of “puzzle-tutorial”) I managed to integrate my Mi Flower Mate in Domoticz, but without this plug-in.

The plug-in has some kind of error with Bluetooth Scan on Raspberry Pi 3: each time the automatic scan mode is invoked it results in a “Scan Error” exit message.

Also, even by switching to manual mode and using Mi Flower MAC Address no data is being pulled.

So, here is what I did instead but please note that:

- I’m running RASPBIAN STRETCH LITE with SID repository enabled due to my needs
- I have a mixed python environment, here you can read the whole thing: https://drive.google.com/open?id=1ZPVI ... nop1wALugx



1) I’ve started installing the required dependencies listed here: https://www.domoticz.com/wiki/Plugins/Mi_flower_mate

2) Then I installed bluez right from sources.

PLEASE NOTE: since I’m using SID repository I was able to install the more recent version of Bluez: 5.49-4. This version works perfectly fine and has support for Bluetooth Low Energy. If you are using standard repository then chances are you will get a 5.23-ish version.

That is a problem because you need at least version 5.44 in order to make things work. So you will have to compile the new version and install manually over the previous one.

In order to do so, you can follow the section in the official wiki here: https://www.domoticz.com/wiki/Mi_Flora_Bluetooth_LE

3) To enable Bluetooth Low Energy features I followed this guide: https://learn.adafruit.com/install-blue ... y-features

4) Reboot your raspberry to apply changes and in the meantime bring the Flower Mate inside near the raspberry.

5) Launch a Bluetooth Scan to find the Flower Mate MAC ADDRESS with the following:

Code: Select all

sudo hcitool lescan
6) Download this script and copy it inside the domoticz plugin folder:

Code: Select all

git clone https://github.com/Tristan79/miflora.git
cp -R ~/miflora/ ~/domoticz/scripts/python/miflora
7) Install the required dependencies:

Code: Select all

sudo apt-get install nstall python3 python3-pip
sudo pip3 install pygatt
sudo pip3 install requests
8) Inside Domoticz I created a new Dummy Device called “Plant” and then added the following virtual sensors:

Soil Humidity – type:percentage
Soil Temperature –type:temperature
Plant Irradiation –type:lux
Soil Fertility –type:custom with axis label: uS/cm2

9) Take note of the IDx of the previously created sensors, in this particular order

10) Locate the domotciz.py file inside miflora folder and edit it with the following:

- At the very beginning insert Domoticz IP, Username and Password (if used)
- At the very bottom delete all lines after the first one (the print lines)
- Customize the print \n1 line with your sensor data: insert a name after the n1: to identify your sensor
- Then in the second line, insert the Bluetooth MAC Address in the first position and then the Sensors IDx in the same order as created.
The result should be similar to this:

Code: Select all

print("\n1: Bouganvillea")
update("C4:7C:8D:60:D4:FA","11","12","13","14")
Save and exit the editor

11) Now for the moment of true: execute the domoticz.py script to read sensor data with:

Code: Select all

/usr/bin/python3 domoticz.py
12) If the read is successful you should see something like this:

Code: Select all

1: My Plant Name
Mi Flora: C4:7C:8D:60:D4:FA
Firmware: 3.1.8
Name: Flower care
Temperature: 27.7°C
Moisture: 30%
Light: 199 lux
Fertility: 1740 uS/cm?
Battery: 80%
13) Now you will just need to add a cronjob to execute the script at your desired interval to update Domoticz readings. In order to preserve battery life in my Flower Care I chose to made two readings a day.

Code: Select all

* */12 * * * /usr/bin/python3 /domoticz/scripts/python/miflora/domoticz.py >/dev/null 2>&1
I agree this is not the best solution, nor the tidiest, but it works.

I hope this might help you too and possibly someone who could develop a working plug-in. :)

I have a question.

My mi flora is working fine on an rasp 2, but i have it running on my second pi (slave) because of the bluetooth distance.
I would like to have this data on my master pi, i tried the master/slave option but the data of the flora is not showing in my master pi (other data is showing) so its only the flora data that is not showing.

Is it possible to add a ip based function in the script, so my master pi can switch the flora switch on my slave pi and receive the data based on ip adres?

Are all the devices available in the master slave settings?

Well I updated today all my 3 rasps to 4.970 version and indeed no master/slave Exchange anymore for the MI Flora sensors :cry:

I managed to broke my association by using android miflower app and connecting it to device, after that it broke. I have tried to remove and installing plugin again, but its a nop go. No devices appears anymore. How do i delete old plugin and install new one correctly ?

Hi,
after the installation of the script, how I add the sensor in the dashboard?
