[Q] Configure charger which is not always connected

[PulsarFX]

In the github readme you state:

setup your Charger in the configuration.yaml (for always connected chargers):

goecharger:
 chargers:
   - name: charger1
     host: <ip of your charger>
   - name: charger2
     host: <ip or hostname of charger 2>

What does the config look like for not always connected chargers? ;)

My charger is offline frequently due to weak wifi signal. No need to configure anything differently. This module handles it gracefully. Just don't expect your input amperage changes to get through after reconnection.

Gracefully? It spams my whole log with errors :-D

it seems to be no difference wheter I use the new or the old config style.

now there is really no difference of the configuration for permanently or non permanently connected chargers. i understand that it is not very helpful for non conntected chargers to report the network timeout :-) will see what i can do to improve this.

[cathiele]

I think about an config option like:

alwaysonline: true|false

to prevent logging of possibly disconnected chargers. What do you think about this?

[PulsarFX]

I'd expect it to not throw errors if it is not available. Maybe a flag could indicate a successful connection to the charger. If not connected, all values would be zeroed.

Can I help with something to get this issue solved?
