Xiaomi Miflora Sensor Integration

ThomDietrich · December 24, 2016, 4:31pm

I don’t think it’s a question of RPi2 or RPi3. Let me look into that in the next couple of days…

skatun · December 24, 2016, 5:04pm

Thanks, Merry Xmas to all… Maybe we can make a java binding at some point aswell,since this plant sensor is the best i have come across so far.

Waiting patiently for BLE support to appear in smarthome / openHAB. After that, I guess the first thing I’ll do is to convert my script based setup to a proper binding

Initial commit of Bluetooth binding and Bluetooth transport bundles

This commit is just to provide visibility and prompt any discussion about API et…c - **it's not considered for merging**. Development is still ongoing and the API is likely to change! This PR currently includes two bundles - a bluetooth (BLE) binding, and a `io.transport.bluetooth` bundle defining an abstract transport API. The transport bundle defines the API and provides a service to allow implementations to register. The concept is that hardware vendors can extend the transport bundle to define the hardware specific implementation. Development is very advanced on an implementation for Linux using the BlueZ library and that will be added to this PR in the near future. The transport bundle provides an API that is very similar to the Android Bluetooth library - I've tried to keep definitions and implementation characteristics the same where possible (and where I can work out what Android does!) to make it easier for documentation and development etc. The binding is far from complete - it is being used to support my debugging at the moment. The API I would consider is largely complete for BLE services at least although the base classes will still be updated. Signed-off-by: Chris Jackson chris@cd-jackson.com

Hey Kim, just writing to inform you that I sadly didn’t find any time to test this till now… Any news on your side?

skatun · January 9, 2017, 10:57pm

@ThomDietrich unfortunate not, I was in germany lately. However when I got home three more of these nice plant sensor had arrived.

They all show nicely up on the bluez bluetooth scan, but I can not compile the pyton script on openahbian, so thats where I am at the moment. I did however start some research to find out if there is an open plant library(to tell us when to water what plant, tell if its not enough light etc)

Is it still python3 gattlib that won’t be installed?
How much did you increase the swap?

Regards, S

skatun · January 12, 2017, 11:12am

Hi I tried searching around on the web for increasing the swap memory, but It seems to be several commands availble, and some says its also dangerous, so is the correct way to do it?

sudo nano /etc/dphys-swapfile 

change
CONF_SWAPSIZE=300


/etc/init.d/dphys-swapfile stop
/etc/init.d/dphys-swapfile start

sudo pip3 install gattlib

sudo nano /etc/dphys-swapfile 

change
CONF_SWAPSIZE=100


/etc/init.d/dphys-swapfile stop
/etc/init.d/dphys-swapfile start

I also came across this database for plants, maybe we can use som regex and grab pictures, waterlevel from it?

skatun · January 16, 2017, 9:48am

Well the file /etc/dphys-swapfile does not exist and /etc/init.d/dphys-swapfile stop is not valid and the whole trying made my OH freeze(worked again after reboot) so I guess I wait for someone else who knows linux to figure it out:) Its minus 10 outside and I can not risk my OH to go down, because then my heating fails aswell…

Seaside · January 16, 2017, 8:10pm

I successfully installed it today on an RPI1 with 512mb memory

Step by step:

Flash and install raspian Jessie Lite 2017-01-11
Put ssh file in /boot/
Raspi-config make sure to set memory split to 16
Reboot
sudo apt-get update; sudo apt-get dist-upgrade
sudo apt-get install git pkg-config libboost-python-dev libboost-thread-dev libbluetooth-dev libglib2.0-dev python-dev bluetooth python3 python3-pip pylint wicd-curses rsync mosquitto-clients python-mosquitto

sudo nano /etc/dphys-swapfile
changed CONF_SWAPSIZE=100 to CONF_SWAPSIZE=500
sudo /etc/init.d/dphys-swapfile restart

sudo pip3 install gattlib

git clone https://github.com/open-homeautomation/miflora
cd miflora
./build.sh

Regards S

ThomDietrich · January 18, 2017, 7:47pm

@skatun I’ve looked into that solution.
The problem is, that openHABian doesn’t provide dphys-swapfile. That’s not directly my decision but I’d say it’s a good one. Still, you should be able to follow these instructions, if you first installed dphys-swapfile following the instructions here:

http://neil.franklin.ch/Projects/dphys-swapfile

After the installation was successful, simply remove or disable it again. Sorry I can’t be of more help right now. Working on other details. Good luck!

skatun · January 19, 2017, 4:18pm

Ok, i will try to look into next week.

sticki · February 3, 2017, 5:29pm

Hello,

I was running into the same problem with my raspi3.
Then I started all over with a fresh openHABian installation … AND

sudo apt-get install git pkg-config libboost-python-dev libboost-thread-dev libbluetooth-dev libglib2.0-dev python-dev bluetooth python3 python3-pip pylint wicd-curses rsync mosquitto-clients python-mosquitto
sudo pip3 install gattlib

Did it for me without swapfile changes … SO, it works

Now running demo.py brings:
Getting data from Mi Flora
FW: 2.8.6
Name: Flower care
Temperature: 21.4
Moisture: 46
Light: 34
Conductivity: 565
Battery: 100

But now both ways from Csongor & Seaside do not work for me …
For the java solution the sproute.properties is missing and I’m not familiar with java … But the idea with the plant files is really good
I’m looking for a mysql solution since this is already running for the thermo rules in OH.

Keep you posted

Cheers Jörg

ThomDietrich · February 3, 2017, 6:34pm

Hey @sticki, that’s good news. Maybe something changed in gattlib in the meantime…

@skatun I feel somewhat sorry, that you had so much trouble with this idea. Please let me know if you did finally succeed. If that is not the case, you could always go with a standard Raspbian installation followed by a manual openHABian run: http://docs.openhab.org/installation/openhabian.html#manual-setup

skatun · February 10, 2017, 10:23am

Swap did the trick to get the gitlib to compile on rpi2, however In openhabian the mqtt fails with httperror 403,
But my question is why would you use mqtt? What if the internet goes down, will it still be able to communicate on local network. Why not use exec binding the python script and the miflora.json to get the values into openhab?

My biggest problem these days are that the rpi2 is running at 100%CPU almost all the time, I do have 270 items, httpbinding, netatmo,huemulator,gpio,dmx binding installed, but struggeling to figure where the bottleneck is… So I put the Miflora on hold untill I can free up some CPU time.

iceatcs · February 10, 2017, 11:52pm

I got demo.py work and return the MiFlora data no problem.
But I’m stuck on the next Seaside’s step 10-11

I have no idea where is sproute.sh? Do I have to create one, or get one from somewhere and where shall I put?

hamwong · February 13, 2017, 1:51pm

hi, I am just getting start with it,
does mine normal with below response?

hamwong · February 15, 2017, 4:16pm

Hi, first have to say thanks for the great works, I am stuck at creating items, I trace and found should due to missing of (SPROUTE_PROPS="/home/pi/sproute.properties"), would you mind explain how should I config this file?
also I found sproute.sh inside jar content is difference with you write in here, will it be a issue?

Knijo_Albert · February 20, 2017, 8:55pm

I bought this item and when it was connet to the phone, it updated th firmware and now i cant connet it again. I can see it from bluetooh but it doesnt connect.
How can i reinstall the firmware?.
Apologize for my english

Olymp · February 21, 2017, 12:33am

Hello! Firmware vryatli you change it back to an older. Tell me, what firmware version you have now? I have everything working on 2.8.6.
