GoodWe GW5048D-ES - set Eco mode power according to battery level

[nzkiwi68]

I'm lucky boy and my power company has a free power period daily!

I'm loving the ability to switch the GoodWe ES to "Eco Charge mode" and then back to "General mode" with a simple HA time of day automation.

I wrote a function in Node-RED to set the ES charger power based on the battery state level. I have listed my simple function below.
My problem is:

• I cannot for love nor money get Node-RED to update the "Eco Charge mode"
• I can't see how in standard HA automation I could run my table to set the charge power according to the battery level.

Any great ideas?
If I could get Node-RED to set Eco Charge mode I'd be away...

My function in Node-RED (to get the idea) - I have 18 kWh storage
// Get the timestamp for node status display
let ts = new Date();
var tsdisplay = ts.toLocaleTimeString('en-GB', { day: 'numeric', hour: '2-digit', minute: '2-digit', second: '2-digit' });
flow.set("tsFlow", tsdisplay);

// Sanity check msg.payload and exit if not a number
if (isNaN(msg.payload)) {
node.status({ fill: "red", shape: "dot", text: "Error! NaN @" + tsdisplay });
return null;
}

// Sanity check msg.payload and exit if not a valid value
var battery = Number(msg.payload);
if ((battery > 100) || (battery < 1)) {
node.status({ fill: "red", shape: "dot", text: "Error! Value:" + battery + " @" + tsdisplay });
return null;
}

// Calculate new Hybrid inverter Charger value based on battery charge state
if (battery >= 90) {
msg.payload = 20;
}
else if (battery >= 85) {
msg.payload = 25;
}
else if (battery >= 80) {
msg.payload = 30;
}
else if (battery >= 75) {
msg.payload = 40;
}
else if (battery >= 70) {
msg.payload = 45;
}
else if (battery >= 65) {
msg.payload = 55;
}
else if (battery >= 60) {
msg.payload = 60;
}
else if (battery >= 55) {
msg.payload = 70;
}
else if (battery >= 50) {
msg.payload = 75;
}
else if (battery >= 45) {
msg.payload = 85;
}
else if (battery >= 40) {
msg.payload = 90;
}
else {
msg.payload = 100;
}
node.status({ fill: "green", shape: "dot", text: "Set Charger:" + msg.payload + "% @" + tsdisplay });
return msg;

I did it!

Here's my UI automation that sets the "Eco Mode power" to a percentage based on the battery level state.
I had to edit in YAML mode the 01:59 set the battery charge power...

So I have 3 UI automations:

1. At time 01:59am set the battery charge power %
2. At time 02:00am - Change GoodWe Inverter Operation mode to eco_charge
3. At time 07:00am - Change GoodWe Inverter Operation mode to general

alias: GoodWe 01:59am set battery charge power %
