Profalux Volets (shutters) with Homekit

Setup

• 2 Profalux volets
• 2 dedicated profalux remotes (1 for each volet) + 1 "global" remote that controls them simultaneously
• Raspberry pi
• ConBee II
• deCONZ
• Phoscon App
• Hombridge
• Homebridge-hue plugin
• Homekit

Profalux remotes programming notes

Finally found the docs on the Profalux site. See...

• Reset a remote (does this just disconnect from an existing Zigbee network?) R x5
• Open the network R then stop
• Join a network R then up
• Copy a remote (make the global remote control the other volets)
  1. The 2 remotes must be in the same network (see open and join above)
  2. On the remote that works with the volet: Up + Down then stop (the volet should move up and down continuously)
  3. On the global remote: R then stop (TODO: verify)

RPI backup stuff

• live image via ssh: ssh pi@homebridge.local "sudo dd if=/dev/mmcblk0 bs=1M" | dd of=./backup.img bs=1M
  • adapted from here
• test the image:

  sudo losetup -Pf ./backup.img
  # find the loopback device that was created, loop8 in my case
  losetup
  sudo mount /dev/loop8p1 /mnt
  ll /mnt
  sudo unmount /mnt
  sudo mount /dev/loop8p2 /mnt
  ll /mnt
  sudo unmount /mnt
  sudo losetup -d /dev/loop8

• shrinking the image: sudo ~/dev/PiShrink/pishrink.sh -d ./backup.img ./backup-shrunk.img
  • https://www.tomshardware.com/how-to/back-up-raspberry-pi-as-disk-image
  • https://github.com/Drewsif/PiShrink
• big compression of shrunk image (from 7GB to 1GB): zstd --ultra -T0 -22 ./backup-shrunk.img -o ./backup-shrunk.img.zst
