Remote HomeAssistant doesn't work if "mobile_app" not active

[denkyem]

Hi

I'm implementing a 2nd instance of HomeAssistant connected to my main one with limited access to entities, services, etc.
This is to give access to guests to some functions, like lights, covers, etc, but I don't want them to change my AC or activate/deactivate my alarm (for example).

So I installed my 2nd instance on docker and I'm deactivating everything that I don't need.
Instead of have "default_config:" on my configuration.yaml, I'm replacing with the integrations that I really need.
For example, I don't need automations, scripts, scenes, etc.

I only need history, logger and person, but for some reason the "remote_homeassistant" needs the "mobile_app" integration or it returns an error and the entities states are not updated.

As soon as I activate the mobile_app integration, the remote_homeassistant works fine.

It is possible that this is not an error and the integration "mobile_app" is actually necessary. Just want to confirm that.

I wonder, do you see the same behaviour as in #245 ?

In my case I got mobile_app active on both instances.
