Feature request - Dynamically recharge Delta Pro battery

[BeyondPixels]

Hi there,

Sorry, it's a bit out of scope but I wanted to dynamically set the "AC Charging power" value of my Delta Pro based on another sensor (excess of solar, basically), a bit like you do with the PowerStream.

I've checked the doc and I can see this:

...But I don't really know how I can use it the way you use "cmdCode": "WN511_SET_PERMANENT_WATTS_PACK" in your py script.

I thought it would be benefit others as well.

Thanks in advance!

EDIT: I've just realized the 2nd screenshot wasn't about setting charging rate but rather setting the max level of the battery.

For now, I use a HA automation which simply switches the smartplug on where the DP is when there is excess solar... And it stays charging at 1000W. I'm not sure how I can dynamically change this value effectively.

So to anyone interested, I figured out by configuring a few things in HA.

First of all, I created 2 automations that start charging the battery when my smart meter says I'm injecting. It's using a smart plug to do so. I've added conditions to avoid start the automation if the smart plug is already on or if the the battery is already above 75%

The other automation is to stop charging when there is no solar available for the battery. Here, I added a second trigger if the PowerStream is providing electricity to avoid charging and discharging at the same time.

Next, I created to 2 template sensors: The 1st one calculates the delta between the AC Charging power of the Delta Pro and the Power from the grid. The 2nd sensor is there to make it round (the step is by 100).

- platform: template
  sensors:
    ecoflow_delta_pro_ac_charging_power_dynamic:
      friendly_name: "Delta Pro - AC Charging power dynamic"
      unit_of_measurement: "W"
      value_template: "{{ (((states('number.delta_pro_ac_charging_power') | float) - (states('sensor.dsmr_power_grid') | float))) | round(0) }}"

    ecoflow_delta_pro_ac_charging_power_dynamic_hundred:
      friendly_name: "Delta Pro - AC Charging power dynamic hundred"
      unit_of_measurement: "W"
      value_template: "{{ ((states('sensor.ecoflow_delta_pro_ac_charging_power_dynamic') | float / 100) | round(0) * 100) }}"

The last thing I did is creating another automation that sets every minute the AC Charging power sensor to the right value. This one isn't pretty but it works.

• If the smartplug is off, than I set the charging sensor to the minimum: 200W
• Else :
• • If the template sensor is below 200W, I set it to 200W
• • If it's between 200 and 2900W, I set charging sensor to the value of the template sensor
• • If it's above 2900W, I set it to 2900W
