Migrating to HAOS from OpenHAB

Configuration
8

To be a bit more specific:

  • There’s no specific openHAB tool, but the individual protocols do include migration.

  • Migrating 40x Z-Wave devices to HA was a case of importing the S0 key, and moving the coordinator across. Most devices “just worked” but a few Fibaro FGD-212 refused so needed a manual reset and add.

  • Zigbee came later for me, so I’ve not tried a migration - guess at a similar process.

  • SmartThings WLAN (i.e. not Zigbee) has an issue at the moment caused by Samsung being rather horrid to their users. For now, my own kit works fine as I have an existing access token.

  • I’ve seen Broadlink devices mentioned, but I made my own using ESPhome ()HA specific Arduino / Tasmota like firmware) and ESP8266.

  • Starting out, I’d use HAOS - this is an appliance locked-down OS like openHABian but with auto-managed containers for HA and Add-Ons (integrations are part of HA), with a Supervisor doing the management. Docker does give more flexibility, but has less features and YOU have to do the work to manage updates.Your cost / benefit may vary.
    I just got a RPi4 and parallel ran HAOS with another RPI4 with openHABian.
