ht_proxy.py never recovers from USB disconnect about hometop_ht3 HOT 4 OPEN

I'll check this. Best to throw an exception and try to reconnect that interface n-times.

from hometop_ht3.

Please update your system with that modified files:

1. ~/HT3/sw/lib/ht_proxy_if.py
2. ~/HT3/sw/lib/ht_release.py

After this update stop and restart that processes with:

1. sudo systemctl stop ht_collgate.service
2. sudo systemctl stop ht_proxy.service
3. sudo systemctl start ht_proxy.service
4. sudo systemctl start ht_collgate.service

Above mentioned problem is fixed with this modification.
Please check it out at your system.
Keep in mind that:
After disconnection and reconnecting the USB port the ht_proxy.py will restart and reopen that serial USBport connection and RESTART also that TCPServer.
So you have to reconnect all previously connected proxy-clients.

ht_proxy now connects wonderfully again, but the basic problem that no more graphs are drawn and no more data is transmitted via mqtt is still there as before ;(

So you have to reconnect all previously connected proxy-clients.

What is the difference between:

before: USB disconnect, reconnect ht_proxy_if.py stops working, ht_collgate.py stops working -> no graphs update, no mqtt upate (frozen)

now: USB disconnect, reconnect ht_proxy_if.py still working, ht_collgate.py stops working -> no graphs update, no mqtt update (frozen)

Isn't it possible to hold the client connections up and running an only reconnect to the USB data source?

Additional observation: The status in the MQTT remains online, although no data has been sent for half an hour...

The MQTT-status 'online' is assigned to the MQTT-client availabilty itself and not to any data-transfer. The 'ht_collgate.py' and it's included mqtt-client are still running, so that MQTT-status must be 'online'.

Yes, this should be possible and a solution. But keep in mind also that socket- and thread-handling is my aim to be improved.
This takes a bit time, so in the meantime don't disconnect that USB-port and use it as a stable connected serial interface.
