Add value_template option

[MacGeyer]

I need to use "analogin" or "virtualanalogin" type but I also need to add some calculations, could you add value_template option please or do you have another solution to map IPX800 sensor formulas to Home Assistant ?

Hello, You should use template entities https://www.home-assistant.io/integrations/template/#state-based-template-binary-sensors-buttons-numbers-selects-and-sensors

Yes I use this workaround currently :

ipx800v4:
  - name: IPX800
    host: "10.0.0.102"
    api_key: "apikey"
    devices:
      - component: binary_sensor
        name: Filtration Piscine
        type: digitalin
        icon: mdi:pump
        id: 1
      - name: RAW PH Piscine
        icon: mdi:water-boiler
        type: "virtualanalogin"
        component: "sensor"

        id: 29
      - name: RAW RedOx Piscine
        icon: mdi:water-boiler
        type: "virtualanalogin"
        component: "sensor"
        id: 30

template:
  - sensor:
      - name: "Calc PH Piscine"
        state: "{{ (((states.sensor.raw_ph_piscine.state) | float) / 100) | round(1) }}"
        unit_of_measurement: ""
      - name: "Calc RedOx Piscine"
        state: "{{ ((states.sensor.raw_redox_piscine.state) | int) - 2500 }}"
        unit_of_measurement: mV

Do you plan to add this to your roadmap ? GCE should add the existing formulas to their API access don't you think so ?

[Aohzan]

No because it's better to you use official template entities like you do, raw value in ipx800v4 integration, calculated value in template, as you will get all supported functions and filters, and nothing to maintain on my side. I don't see what is the "existing formulas" ?

[MacGeyer]

When using analog entries (virtual or not) in IPX800 you can add formulas at http://X.X.X.X/admin/analogVirt.htm like I did for the X200-PH This way iin IPX800 raw values will never have be used, I think it shouldn't have to be used in status or API anyway ! https://wiki.gce-electronics.com/index.php?title=X-200PH#Valeur_.3E_Analogue

ahhh indeed I don't understand why GCE doesn't return the real value :thinking: maybe you can ask them ?
