how did you interface to the modbus interface ?
G
Using this integration: GitHub - sfstar/hass-victron: Integration for Home Assistant to fetch data from the victron gx device via modbusTCP
let me ask different, did you connect a physical RS485 dev board to the RS485 port on the victron ?
assume RS485 connected to the HA ?
G
Sorry George - missed that part. I run a CerboGX and connect to the Cerbo Modbus using the integration above from a Home Assistant instance on a Pi. The above sensors are then available on the HA to use on the Energy Dashboard.
Let me stop there… that’s about as far as I can go without running out of knowledge…

You all know that Victron now has Forecasting and that you can get that data via the new Victron VRM API?
It was posted on this forum before.
Just wondering.
… actually found I previously deployed some code in NodeRed that does Modbus calls to the victron… so it’s been lying there, simply not used,
I’m changing my source from MQTT → Modbus.
G
did not know… but this is in victron. i want it inside HA.
G
anyone have a idea why i’m not showing forecast day 2 etc.
I have Solcast installed
2nd question, how can I stretch the image to fill a page, I pasted code into a vertical stack card, alternate suggestion appreciated.
@Sc00bs - this is “copy” from your dashboard, porting it to fit into my Victron based system… about now where those generic naming of values would be loved
you also use a entity:
- entity: sensor.solcast_forecast_remaining_today_every_minute
This does not show in available entities for solcast ?
You need to update the apex code.
Should look something like this:
- entity: sensor.forecast_today
name: Solar Forecast (D1)
extend_to: false
color: grey
opacity: 0.3
stroke_width: 0
yaxis_id: kWh
show:
legend_value: false
in_header: false
data_generator: |
var today = entity.attributes.detailedForecast.map((start, index) => {
return [new Date(start["period_start"]).getTime(), entity.attributes.detailedForecast[index]["pv_estimate"]*2];
});
var data = today
return data;
Emphasis on: var today = entity.attributes.detailedForecast.map((start, index) => {
You probably not having detailedForecast in there.

So you see you have a couple of different lines reading:
data_generator: |
return entity.attributes.forecast.map((entry) => {
return [new Date(entry.period_start), entry.pv_estimate];
});
That needs to change to
var today = entity.attributes.detailedForecast.map((start, index) => {
return [new Date(start["period_start"]).getTime(), entity.attributes.detailedForecast[index]["pv_estimate"]*2];
});
return today;
Or you can do this (not tested by me):
data_generator: |
return entity.attributes.detailedForecast.map((entry) => {
return [new Date(entry.period_start), entry.pv_estimate*2];
});
You need to do the change for each one.
