I don't really understand this, surely the reserve setting for the inverter in apps.yaml should just point to 'number.sigen_plant_ess_backup_state_of_charge'?

It could do but its not in the template.

What would the entry in apps.yaml be for this to work?

the entry in apps.yaml would be:

  reserve:
    - number.sigen_plant_ess_backup_state_of_charge

However, just adding that, I don't think predbat will recognise the reserve configuration as the SIG inverter definition coded in predbat has that Sig inverters don't have a reserve control.

To fix this, and to test this change, you need to edit 'config.py' in the predbat addon directory, search for "SIG" to find the inverter definition.

It will look like this:

    "SIG": {
        "name": "Sigenergy Sigenstor",
        "has_rest_api": False,
        "has_mqtt_api": False,
        "output_charge_control": "power",
        "charge_control_immediate": True,
        "has_charge_enable_time": False,
        "has_discharge_enable_time": False,
        "has_target_soc": False,
        "has_reserve_soc": False,
        "has_timed_pause": False,
        "charge_time_format": "S",
        "charge_time_entity_is_option": False,
        "soc_units": "%",
        "num_load_entities": 1,
        "has_ge_inverter_mode": False,
        "time_button_press": False,
        "clock_time_format": "%Y-%m-%d %H:%M:%S",
        "write_and_poll_sleep": 4,
        "has_time_window": False,
        "support_charge_freeze": True,
        "support_discharge_freeze": True,
        "has_idle_time": False,
        "can_span_midnight": True,
        "charge_discharge_with_rate": False,
        "target_soc_used_for_discharge": True,
    },

change the line "has_reserve_soc" from False to True

Give it a go and let me know

Thats working as expected. Want me to raise that PR or you happy to?

I'll do it as part of the documentation update, thanks for confirming it works.

Have just responded to you on the freeze charge change
