Hello,
I installed home assistant in ihost docker and zha with sonoff dongle zigbee plus.Now i want to install zigbee2mqtt but not recognize my dongle.I uninstall home assistant and try to install again with zigbee2mqtt but seem to not recognize the dongle.I need to reset to factory the ihost or format the card to be able to install with mqtt?
No, you don’t. See this video.
Z2M and ZHA can be run on the same HA instance as long as you have 2 coordinators. No interference issues as long as you keep separate Zigbee channels. ZHA defaults to 15, Z2M defaults to 11, so there are no out of the box conflicts.
Home assistant is installed in docker on iHost and do not recognize de dongle automatically.
I had a previous variant of HAS installed on docker iHost and used the dongle to install ZHA,I uninstalled this version of HAS but when i try to install a new version with zigbee2mqtt is seem that don’t recognize the dongle from the iHost usb port.
Read this How to Set Up Zigbee2MQTT with Docker or this How To Pass Through USB Zigbee Devices To Home Assistant Running In Docker.
