Noticed that the Abode integration only allows a single instance. If you try to add a second, it says, " Already configured. Only a single configuration possible."
Many other integrations allow multiple instances and I’m wondering if there’s a “standard pattern” for HA integrations to allow multiple instances. If it’s straight-forward, I can submit a PR for it, but don’t want to reinvent a wheel.
This decision is impacting very core of development of integration;
storing state data and separation of data of the same integration and different instances
generating unique id for each instance
setting up services and consuming them (integration.lock() vs integration.lock(instance) vs instance1.lock())
Any integration can be converted into multi instance supported but it requires a migration for existing users as their unique ids for existing instances should be updated respectively.
