[TUTORIAL] Setting up MQTT on Homey for configuring Home Assistant for dashboard purposes

[HarriedeGroot]

Wrote some logic to retry topic subscription on failure. If a subscription fails, Homey does not listen to triggers from outside apps. Maybe this helps addressing the above problems.

Submitted (waiting for approval).

Version 2.1.9

• Retry topic subscriptions on failure & manual broadcast

Already available on the master branch.
