Home assistant sensors not available

[OnktheMonk]

I cannot get the sensor info available in HA I see the attributes and added the example code in configuration.yaml I can add them in cards but they display no info. Also did a restart.

[tarmor1]

Maybe could you share some example from configuration.yaml and print screen on how they display in cards?

If you need any other info. Please let me know.

Hi! You defenitely need value_template to be populated. https://www.home-assistant.io/integrations/template#value_template This is how I have the DHW tank temp (it's in HA terms "legacy template"), but works still. Anyway, you definitely need to have it set.

      dwh_water:
        friendly_name: "DHW tank temp. (R5T)"
        unit_of_measurement: '°C'
        value_template: "{{ state_attr('sensor.althermasensors', 'DHW tank temp. (R5T)') }}"

Try your value template out in Home Assistant Developer Tools > Templates: .. and you can observe the actual value (43C in right side taken from the Attribute set by espaltherma)

[OnktheMonk]

That was the issue! Works now. Thank you for the info!

@OnktheMonk, how did you manage to get the energy info into HA? Which unit model do you have and what config file do you use? I can't seem to read this info from my Altherma.

[OnktheMonk]

Yeah I get the info. But I have some issue with connectivity, I guess bad Dupont connectors. I orded a correct connector for the pcb and I'm waiting for them to arrive. Then I'll continue this project. Now I lose connection every half hour.

I have the EHVX08S23EJ6V.

I have the EHVX08S23EJ6V.

Alright, but which /include/dev/file.h do you use?

[OnktheMonk]

I used this one: #include "def/ALTHERMA(LT_DA_04-08KW).h"

[AbeltjeNL]

I used this one: #include "def/ALTHERMA(LT_DA_04-08KW).h"

Alright, thank you. Can you tell me how you managed to read the or make the energy sensors in HA? I can't seem to wrap my head around it. Are you using the COP calculation?

[OnktheMonk]

Not yet but I parked the project because of the connection loses until I get the right connectors.

Here you can find a very good explanation (in Dutch) to get the info. But I guess that wont be an issue.

Dankjewel! 😁

I have a similar Issue, all of the data comes through in MQTT, however when I set:

      dwh_water:
        friendly_name: "DHW tank temp. (R5T)"
        unit_of_measurement: '°C'
        value_template: "{{ state_attr('sensor.althermasensors', 'DHW temperature(R5T)') }}"

it returns ""None"

This happens with all the entities, any help appreciated.

Hi!

        value_template: "{{ state_attr('sensor.althermasensors', 'DHW temperature(R5T)') }}"

Are you sure your MQTT main element is sensor.althermasensors? You get None if either attribute or main element is misspelled...

And btw, I recommend moving to the non-deprecated notion of sensors. This is how I have it. Using this you get as well HA Statistics and some other nifty stuff, eg getting icons according to device classes.

template:
  - sensor:
      - name: "LW setpoint (main)"
        unit_of_measurement: '°C'
        device_class: temperature
        state_class: measurement
        state: >
          {{ state_attr('sensor.althermasensors', 'LW setpoint (main)') }}

(And the binary states eg Booster heater, BUH heaters etc define as binary_sensor under template):

  - binary_sensor:
      - name: "Defrost Operation"
        device_class: power
        state: >
          {{ state_attr('sensor.althermasensors', 'Defrost Operation') }}

Thanks, I has the name incorrect somehow it was : sensor.altalthermaermasensors

This Code Works:

template:
  - sensor:
      - name: "LW setpoint (main)"
        unit_of_measurement: '°C'
        device_class: temperature
        state_class: measurement
        state: >
          {{ state_attr('sensor.altalthermaermasensors', 'LW setpoint (main)') }}

I have updated the sensor names and shared them here, Thanks for the help:
