Migrating to HAOS from OpenHAB

[mjeshurun]

Hello Friends,

For the past few years I’ve been running my smart home using OpenHAB installed on Unraid as a docker container.

Everything is working ok with my current system, but I’m thinking of switching to HA.

Can anyone please share what I should take into consideration for the migration process?

My smart home has Zwave, Zigbee, SmartThings Wifi devices, and RF devices, which I control using: Zwave usb controller, Zigbee usb controller, and a Broadlink RM4 Pro for controlling RF devices.

If I switch to HA and connect my current Zwave and Zigbee usb controllers, will HA be able to automatically find and add all the Zwave and Zigbee nodes I included and configured in OpenHAB, or will I first need to exclude these devices from OpenHAB and then include them on HA?

Is there an easy migration assistant I can use that connects HA to OpenHAB for an automatic import of my OpenHAB configurations?

I hope someone can help

Hi, and welcome to the HA community,

Migration or parallel running of openHAB and HA is a well trodden path with lots of information (just use the search)…

Migration from OpenHAB to HA

Hi, and welcome to the HASS community, I parallel ran openHAB and HASS for a year, rewrote automations, then moved over several years ago so know exactly the switch from Java(ish) to YAML. I still kind of miss complex tech posts from rlkoshak on the forums! Top Tip Parallel-Run openHAB and HASS using one MQTT broker for both platforms. Publish from one to the other where needed. Since then, HASS has become much easier to configure with many areas auto-configuring (something I first hated in…

openHAB and Home Assistant on same Raspberry Pi 4

Hi, I parallel ran openHAB and HASS on separate RPi for over a year before moving fully to HASS. This worked well, with a single MQTT broker acting as a comms path when cross-platform automation was needed. After writing years of Java(ish) complex scripts on openHAB, I though YAML automation was going to be a toy - but in the end, the same functions ported across with about 1/10 the total lines of code. Basically the jump from openHAB2 to openHAB3 was much worse than moving to HASS! You don’t…

Crossover from OH to HA and MQTT item config

Hi Neil, I ported my system across from openHAB to HASS some years ago after several months of parallel running with one MQTT broker. Both openHAB and HASS connected to the same instance of Mosquitto allowing automations and other config to be ported across one by one. Similar to openHAB 2.0, MQTT devices can be defined manually or using HASS auto-discovery. The latter works is much easier for devices that support it (e.g. older Tasmota) as you configure the device once, not the automation pla…

If your using docker

HA in docker may be better than HA OS

[mjeshurun]

Thank you for your suggestion

Can you please explain why it would be better to run HA in docker in my scenario?

If I understood the HA documentation correctly, in HAOS all the addons are installed, configured and updated from within HAOS, whereas, in docker I will need to manually install, configure and update each addon separately, and only later connect the addons to HA.

Did I understand correctly?

Thank you very much, James
I will take the time to read these threads.
I hope I will find a good solution in one of them

Nope you’re correct

My personal preference is haos. I have no desire to be a Linux or docker administrator. But the flexibility is there if you want.

I presume if you are using docker you have other services in docker already and you know how to manage docker

Docker is more flexible in my opinion and I don’t like VMs.

My recommendation is a mix of my preference and logic based on presumption of your current setup

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.

Documentation

Architecture sketch (more detailed than the docs):

2025.1: Backing Up into 2025!

[image] Integrations are part of Core Add-ons are containerised services

As to the HA Container (HA running in docker solely managed by the user) or HAOS (HA running in docker but solely managed by the supervisor along with all add-ons) question…

do you have any docker containers that aren’t home automation related? not all docker containers have equivalent add-ons. If you are running any of those then if you run HA OS you won’t be able to use those on the same machine (easily…). Otherwise you should probably use HA OS.
