Export power limit unexpectedly set to 0

[korttoma]

Anyone know why this Automation would spontaneously set the Export power limit to 0?

Or does this automation just fetch the value from Inverter?

I am just trying to find out why it was changed to 0 because the inverter started to limit the export without me changing anything.

Interesting 'glitch'....

The upper automation is triggered, when the mobus register (export_power_limit) of the inverter was changed and updates the input number value "set_sg_export_power_limit"

The second automation is triggered by changes of the set_sg_export_power_limit input_number and writes the modbus register (export_power_limit).

Or does this automation just fetch the value from Inverter?
Both automations ensure that the GUI is up to date with the modbus register values.

I assume the export_power_limit was somehow 0 in you case.

When did this occur? Was ist just after a restart or in the middle of operations (maybe fw update?)

I checked the Logbook and found that I actually had another Automation setting the value to 0 when Nordpool prize goes too low so that I am not selling energy at a negative prize. Totally forgot about this automation as it was now the first time it was triggered.

So the updating of the slider worked as expected. Thank you for taking the time to explain how it works and for working so hard on making this implementation so amazing!
