Hi everyone 
,
Building on quasar66ās description of his setup, I have created a similiar solution to his, which is setup easily using Ansible playbooks. It runs on Docker swarm and creates a stack running Home Assistant, MariaDB in a Galera cluster and Mosquitto broker.
The project is called HAHA - Highly Available Home Assistant, you can check it out in this thread: HAHA - Highly Available Home Assistant
Thanks to quasar66, I hope the project helps you out!
Thank you for the description of your design @quasar66 . Can you please explain how does āall devices are either from mqtt or use another type of network detection, so it does not matter where the device isā work? If a Z-Wave based sensor is connected to node n1 and n1 fails. How would you get events from the sensor?
You wouldnāt. What they mean is that the devices in use are controlled over the network, and as such can be accessed from any node, in contrast to a Z-Wave stick or other directly connected which can only be attached to a single host.
devices = the computers HA runs on? or the Z-Wave devices?
hi i was wondering if any of you guys had this working as a non Dockerā¦ but running OS version of home assistantā¦ i asked for a feature request
https://community.home-assistant.io/t/home-assistant-cluster-feature-request/377975/4
as i run HA Supervisid OS in a VM under unraid
my current solution is i set it upā¦ shut it down copy to my 2nd unraid boxā¦ power up the VM change my name to backupHomeā¦ and my main is HomeAssistant
so i have a failoverā¦
have you guys been able to tackle it in the OS you create a dashboard and it instantly updates the dashboards on the backup home assistants? does that docker thing work there for the OS version?
so i can have like 3 identical KVM VM OS version runningā¦ as the Docker of HA in unraid not as good as the VM
