more then one solarcharger possible?

[Oldie-driver]

was nice, if i can use more then one solarcharger. Using just one eps32 für every solarcharger ist not a good option.

My first quick try work with bad side effects.

I would have to derive an object from the class victron_ble for each charge controller, like victron_ble_id and victron_ble_id1. But I have no idea how to phrase that.

Is there a solution for this in ESPhome, or do I have to try a new fork?

I have connected 3 solar charger and one shunt to one esp32. What is your issue in doing it? Can you share your config?

The problem is in the energie dashboard in Home Assistant

i make a try in this wrong config way:

victron_ble:

• id: MySmartSolar mac_address: ${smart_solar_mac_address} bindkey: ${smart_solar_encryption_key}

• id: MySmartSolar1 mac_address: ${smart_solar_mac_address1} bindkey: ${smart_solar_encryption_key1}

  • platform: victron_ble victron_ble_id: MySmartSolar name: "Battery Voltage" type: BATTERY_VOLTAGE
• platform: victron_ble victron_ble_id: MySmartSolar name: "Battery Current" type: BATTERY_CURRENT
• platform: victron_ble victron_ble_id: MySmartSolar name: "Yield Today" type: YIELD_TODAY

....

• platform: victron_ble victron_ble_id: MySmartSolar1 name: "Battery Voltage" type: BATTERY_VOLTAGE
  • platform: victron_ble victron_ble_id: MySmartSolar1 name: "Battery Current" type: BATTERY_CURRENT
  • platform: victron_ble victron_ble_id: MySmartSolar1 name: "Yield Today" type: YIELD_TODAY

The field YIELD_TODAY make the Problem in the energie dashboard

In the overview dashbord, the values ​​of the charge controllers are shown alternately. But it looks as if it is the same device with alternating different data.

This make a problem in the energie dashboard. Charger one maybe have Yield_today 100Wh, charger tow have 600Wh as example

HA see, Yield_today 100Wh, then 600Wh. HA mean, 500Wh in this few seconds after see 100Wh, ok, is now only 100Wh, ignore. Then 600Wh see again, 500Wh more, count this again. Around every 20 seconds HA think, i got 500Wh ~ 3~4x in minute, 60 minutes on a hour. So see around 900kWh in one hour.

In any case, on raining afternoon, the energie dashboard say, i got more electric power, then i need in one full year with 2 people.

I need for evey charger at last for YIELD_TODAY a unique entity. I have no idea, how i make this in the yaml config, inside c++ is very easy.

(Sorry, English is not my native language )

Okay the problem is the energy dashboard in HA and not the integration. I don't use / have any HA running. I use ESPHome without HA. You can try aggregating the values on the esp. So for HA it is presented as one value. See example in issue #46.

i am so stuppid, maybe just to old..... The solution: The variable names simply need to be renamed

As an example:

• id: MySmartSolar mac_address: ${smart_solar_mac_address} bindkey: ${smart_solar_encryption_key}
  • id: MySmartSolar1 mac_address: ${smart_solar_mac_address1} bindkey: ${smart_solar_encryption_key1} .....
• platform: victron_ble victron_ble_id: MySmartSolar name: "Battery Voltage" type: BATTERY_VOLTAGE
  • platform: victron_ble victron_ble_id: MySmartSolar name: "Battery Current" type: BATTERY_CURRENT
  • platform: victron_ble victron_ble_id: MySmartSolar name: "Yield Today" type: YIELD_TODAY ....
• platform: victron_ble victron_ble_id: MySmartSolar1 name: "Battery Voltage1" type: BATTERY_VOLTAGE
  • platform: victron_ble victron_ble_id: MySmartSolar1 name: "Battery Current1" type: BATTERY_CURRENT
  • platform: victron_ble victron_ble_id: MySmartSolar1 name: "Yield Today1" type: YIELD_TODAY .....

So Home Assistant see both and can work with this. Maybe as an example Yaml Config file or just a hint in the readme ?
