and " * ChromeCast integration: settings to enable connection keep-alive through device polling."
could some advise what the settings (no documentation) do on the app page, eg what is getting polled? why the option to very the poll interval? and whether we now still need to initialise GH speakers frequently (eg Chromecast helper)

[gopher.ny]

It's polling ChromeCast status every N seconds to keep the connection alive.

I've put in seconds selection because I have no idea what's going to work best out there. For internal testing, 15 seconds (default) was just fine, but we haven't really experienced the sort of issues that pop up in the community. Thus an option to fine tune things, depending on the feedback.

so increase the time till it breaks!
so should the stop the need for us to send periodic initialise() commands (eg chromecast helper)?

I have 7 devices to ping, is there a limitation? Ping 7 device each 15 sec, is this not to much load for the hub?

Yeah

I hope this change makes the connection more stable/reliable, that's all I'm going to say...

No, it's a very basic request. Not trying to do anything fancy here.

@kilowatts

Unfortunately I can't get group speakers to work at all with .141

Don´t know about a speaker group, a speaker pair is working
