RFXTRX integration doesn't recover from a dropped network connection to an RFXTRX, requires HA restart

The problem

I have an RFXTRX433 device, connected to Home Assistant via a tcp connection.

This works well in normal operation. However, if the TCP connection is interrupted due to a network issue (e.g. RFXTRX is at a remote location and broadband is interrupted), then Home Assistant loses connection to it. This state can’t currently be recovered from when the network connection is restored without restarting the whole of Home Assistant.

I suggest one of the following is considered:

1. The RFXTRX integration with Home Assistant monitors the health of the TCP connection to the RFXTRX, and if it drops, attempts to restart it on a timer
2. The RFXTRX integration exposes a rfxtrx.reconnect service which can be called by an automation (for example, one could detect a lack of rfxtrx events and use this to trigger the reconnect service)

Environment

• Home Assistant Core release with the issue: 0.114.1
• Last working Home Assistant Core release (if known): N/A
• Operating environment (OS/Container/Supervised/Core): HassOS 4.12
• Integration causing this issue: RFXTRX
• Link to integration documentation on our website: https://www.home-assistant.io/integrations/rfxtrx/

Problem-relevant configuration.yaml

Still a valid issue for me. Even reload does not work for me.
