Overnight stops updating #56

Closed nagydavid closed 2 years ago

Hi @solmoller,

I just want to explain a bit better my question, which I mentioned in the PR. Specs.: Hardware.:

When there is production(sun) everything works. Getting data, sub main_loop() operates, etc. But when production seize (night), then the loop seems to freeze. Also when I restart the script, during offline ours then I get the following:

2021-12-21 19:47:04: Severity 1, Configfile is: eversolar.ini

last four line repeats itself, with increasing intervals of (10-30-40-50....etc.)

My config looks the following.:

[options]
query_inverter_secs = 50                # how often to request data from the inverter and write to log file
debug = 4                               # Debug level , 0 = none, 1 is high priority, 3 is everything, 4 also output packets sent to and received f>
log_file = "/var/log/eversolar"         # make sure the user executing the script can write to this file
output_to_log = 1                       # 1 = output to the above logfile, 0 do not
clean_log = 1                           # Cleanup log file every month, 0 = disable, 1 = enabled (default)
communication_method = "serial" # "eth2ser" or "serial". defines wether you are using an ethernet to serial converter to connect to the inverter, o>
strings = 2      # number of PV panel strings (panels wired together) connected to your inverter. 1 or 2 supported.

[serial]                                # communication_method must be set to "serial" above for serial comms
port = "/dev/ttyUSB0"

Apart from my newly proposed MQTT feature, everything is disabled.

I just would like to ask to take a peak if I have made some error

That all looks very fine, both log and config

I suggest you simulate 'night'

There are many feasible ways of doing this, some even faster than waiting for an eclipse. Some are simpler than throwing a blanket on the panels. At night the inverter is powerless, but I think that unplugging the serial cable while the system is not communicating may have the same effect to your software.

It's the darkest day of the year here in Denmark, we have plenty of 'night'

perfect, i will try it out tomorrow :)

I'm closing, I think it was related to the influx setting which halted the update, when I turned it off, and only the mqtt is enabled, everything worked as intended
