- Raspberry Pi 4
- mi flower sensor
- Royal Gardineer works for me just search on amazon on pearl you find the cheapest one. The most important thing is that they are based on Xiaomi Flower. µ
On mac search for disk diskutil list
download rasbian image I used 2020-05-27-raspios-buster-full-armhf.img link to current rasbian image!
Then copy image to sd card with diskutil
First unmount: diskutil unmountDisk /dev/diskN, for me it was disk2. Afterwards you should see a output of_ Unmount of all volumes on disk2 was successful
Switch to the download folder and then copy the image with sudo dd bs=1m if=2020-05-27-raspios-buster-full-armhf.img of=/dev/diskN; sync, replace diskN with the disk you found under diskutil list.
Put disk again in raspberry and start.
Clone the repo and build the docker docker build -t pygarden ..
Afterwards start the container with : docker run -e TZ=Europe/Amsterdam --rm -it --privileged --network host -v /home/pi/workspace/pygarden/output/:/output/ pygarden "--init"
Images is built on raspberry pi with arm32v7 as base.
With crontab -e we add the following line:
*/1 * * * * /usr/bin/docker run -e TZ=Europe/Amsterdam --rm -it --privileged --network host -v /home/pi/workspace/pygarden/output/:/output/ pygarden
To check the database install sqllite3
sudo apt-get install sqlite3
change to output folder of pygarden
sqlite3 -column -header
.open "sensor_data.db"
SELECT * FROM sensor_data;
You can dump the tabel to output as data_sensor.csv
/usr/bin/docker run -e TZ=Europe/Amsterdam --rm -it --privileged --network host -v /home/pi/workspace/pygarden/output/:/output/ pygarden "--export"
With crontab -e we add the following line for a 30 minutes interval export:
*/30 * * * * /usr/bin/docker run -e TZ=Europe/Amsterdam --rm --privileged --network host -v /home/pi/workspace/pygarden/output/:/output/ pygarden "--export"
To visulize data simply call :
docker run -e TZ=Europe/Amsterdam --rm -it --privileged --network host -v /home/pi/workspace/pygarden/output/:/output/ pygarden "--visualize"
You will find an rendered graph in output/html/index.html
To access the renderd graph, you can use the lightweight http server ```
install it via sudp apt-get install lighthttpd
Go to lighthttpd.conf and add at server.document-root = "/home/pi/workspace/pygarden/output/html/"
Then restart lighthttpd sudo service lighthttpd force-reload
