[Errno 107] Socket not connected

[Crashman1983]

This happened a few times since I started to use the new version of Luxtronik. Have not seen this before. It results on complete loss of all entities (unavailable) until I restart HA.

@Crashman1983 I have added a handling in the main branch. Please try the main branch.

Hi!

i installed the main branch yesterday. I got another Error today, but your fix seems to be successful in terms of keeping the integration running.

But is it possible, that the integration sends incorrect values for heat amount when this error occurs? I am using a template sensor to add dhw_heat_amound and heat_amount_heating to heat_amount_total.

  - unique_id: luxtronik_heat_amount_total
    unit_of_measurement: "kWh"
    device_class: energy
    state_class: total_increasing
    availability: >
      {{ states('sensor.luxtronik_310312_0495_heat_amount_heating') not in [ unknown, unavailable, none ] and
           states('sensor.luxtronik_310312_0495_dhw_heat_amount') not in [ unknown, unavailable, none ] }}
    state: >
      {% set t = states('sensor.luxtronik_310312_0495_heat_amount_heating') | float %}
      {% set u = states('sensor.luxtronik_310312_0495_dhw_heat_amount') | float %}
      {{ (t+u) | round(1) }}

Whenever this happens, the template sensor jumps to zero, and after restart of the integration, the new template_sensor value is slightly lower, than before. I cannot explain that behavior.

What I can see is a kind of peak in heat_amount_heating, that I can't explain as well.

If the values could not updated, e.g. network error, the sensor values should become the "unavailable" state. But I think this is a bigger change. E.g. in a future release.
