Luxpower inverter support

[nickjf20]

MQTT bridge: https://github.com/celsworth/lxp-bridge

Preliminary app.yaml: https://github.com/nickjf20/lxp-predbat/blob/main/app.yaml

This is read only at the moment. I haven't looked into adding services to control charging/discharging. Any help appreciated.

Consumption is currently not calculated by lxp-bridge. Add a helper like this: https://github.com/celsworth/lxp-bridge/issues/232

Trying to add charge control: https://github.com/nickjf20/lxp-predbat/blob/main/mod https://github.com/nickjf20/lxp-predbat/blob/main/app.yaml

LXP bridge allows AC charge time slots but in the format "00:00-00:00". (Start - End). I'm unsure how to integrate this. For output_charge_control: "power", what does this function do?

[rossetf]

I ended up using some helpers as attributes to hold the values (set via predbat) I then used an automation to update the charge slot when either or the helpers changed values, not the most performant but then it doesn't need to be. I no longer use the same LXP integration as you, so my memory is a little cloudy although I have similar issues in the one I am using and am again using helpers to set the final lxp attributes

Hi Rossetf, are you using Guy's integration? Unfortunately it doesn't work with my BH dongle.

Could you share an example of your helpers and I will see if I can translate it to lxpbridge?

Hi Nickjf20, I am, I will try to put an explanation together for you later tonight.

I am Using Guy's integration, and so far so good

My apps.yml looks something like

 inverter_type: "LP"

  inverter:
    name: "LuxPower"
    has_rest_api: False
    has_mqtt_api: False
    output_charge_control: "none"
    has_charge_enable_time: True
    has_discharge_enable_time: True
    has_service_api: False
    has_target_soc: True
    has_reserve_soc: False
    has_timed_pause: False
    charge_time_format: "HH:MM:SS"
    charge_time_entity_is_option: False
    soc_units: "%"
    num_load_entities: 1
    has_ge_inverter_mode: False
    time_button_press: False
    clock_time_format: "%H:%M:%S"
    write_and_poll_sleep: 10
    has_time_window: True
    support_charge_freeze: False
    support_discharge_freeze: False
    has_idle_time: False
    can_span_midnight: True

with the time related stuff as below

 scheduled_charge_enable:
    - switch.lux_ac_charge_enable
  scheduled_discharge_enable:
    - switch.lux_force_discharge_enable
  charge_start_time:
   - input_text.charge_start_time
  charge_end_time:
   - input_text.charge_end_time
  discharge_start_time:
   - input_text.discharge_start_time
  discharge_end_time:
   - input_text.discharge_end_time

As can be seen the helpers listed in for example charge_start_time are just text based helpers which batpred is more than happy with.

I then use automations so when the helpers change the correct lux value is set up (in Guys these are type time) such as this one

alias: Charge Time Change - Start
description: ""
trigger:
  - platform: state
    entity_id:
      - input_text.charge_start_time

condition: []
action:
  - service: time.set_value
    metadata: {}
    data:
      time: "{{ states('input_text.charge_start_time')}}"
    target:
      entity_id: time.lux_ac_charge_start1
    enabled: true
mode: single

Which for you I think will look something like

alias: Charge Time Change - Start or End
description: ""
trigger:
  - platform: state
    entity_id:
      - input_text.charge_start_time
      - input_text.charge_end_time
condition: []
action:
- service: text.set_value
    metadata: {}
    data: 
      option: "{{ states('input_text.charge_start_time')}}-{{ states('input_text.charge_end_time')}}"
    target:
      entity_id: text.ac_charge_timeslot_1
mode: single

You would also need something based off this for discharge times.

Hope that helps.
