LuxPower - How to set discharge SOC limit?

[s1dave-web]

New to batpred but have it working with my LuxPower 3.6kw Hybrid Inverter using guybw/LuxPython_DEV addon.

I can see it adjusting charge SOC limit and setting charge times to match the octopus low prices - great

I can see it also adjusting the force discharge times and enabling the discharge... but I do not see it manipulate the discharge SOC limit

Looking at the apps.yaml template the charge limit is set by this property:
charge_limit:
- number.lux_ac_battery_charge_level

I do not see any option for the discharge limit.

Should there not be another setting for the discharge limit such as:
discharge_limit:
- number.lux_forced_discharge_battery_level

Or is batpred controlling the discharge level using another method?

Have you tried defining this extra entry in apps.yaml and see if it works?

[s1dave-web]

Added to apps.yaml - just need to wait till 5pm now when it will hopefully set the limit to 46%

I am also seeing this warning every 5 minutes in the logs:
Warn: Inverter 0: Using inverter type LuxPower - not all features are available

What features are not available?
Can the frequency of this warning be lowered?

Adding discharge_limit seems to make no difference, I don't think the script knows it can set a discharge limit.

There is no discharge_limit option in batpred, you have to automate yourself. Batpred will control the charge_limit entity, for both charge and discharge, so you just need to sync these

[s1dave-web]

@springfall2008 does pretbat have the ability to set a discharge limit or does it just monitor/predict the discharge % for a given export window and stop when it gets to the intended limit?

[raldred]

@s1dave-web So our Lux inverters have separate charge and discharge target.
You need an automation to keep them in sync when using batpred since it uses a single target SOC entity

This automation will update your lux_forced_discharge_battery_level entity to match the lux_ac_battery_charge_level which batpred is controlling, if predbat_exporting is "on", if you've based your config from the lux template I contributed.

Thank you for the help - I will test this out 👍
