Migrating to HAOS from OpenHAB

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…
