A5-10-06 (Eltako)

[HotteX]

Cheerio,

a request for a "Thermostate" by Eltako. I got part of the mapping working fine but this device has 2 specialities, that are too complicated for my current state of knowledge:

1st: Temperature. This works.

2nd: A setpoint. I get the raw value in my entity, but it would be more helpful to have a temperature value.
According to specs that means: Value * 0,157°C (just like TMP, only not reversed. TMP is 255..0)
Eltako writes:
Data_byte2 = 0..40°C (0..255)
Set Point range: 12..28°C

3rd: A slide switch with 3 states (Day, Off, Night with values 1 and 0 (off being really off it seems).

Hi @HotteX,

If I understand correctly, you tried to add the support for A5-10-06, right ?
If so, could you please share your code ?
It will be easier to understand.

From your other message in #32, you wrote that your configuration for your A5-10-06 is:

[Temp/Eltako_1]
address         = 0xFFB17E00
rorg            = 0xA5
func            = 0x10
type            = 0x06

But from your log here, it seems that the address is 0xFFA0C800 / 0xFFA0C80. It this correct ?

[mak-gitdev]

Ok I see,

So what you can try is:

0xA5:
   0x10:
      0x06:
         device_config:
            command: ""
            channel: ""
            log_learn: ""
         entities:
            - component: "sensor"
              name: "t_raw"
              config:
                 state_topic: ""
                 value_template: "{{ value_json.TMP }}"
                 device_class: "temperature"
                 unit_of_measurement: "°C"
                 enabled_by_default: "true"
            - component: "sensor"
              name: "tempC"
              config:
                 state_topic: ""
                 value_template: "{{ value_json.TMP | round(1) }}"
                 device_class: "temperature"
                 unit_of_measurement: "°C"
            - component: "sensor"
              name: "setpoint"
              config:
                 state_topic: ""
                 value_template: "{{ (value_json.SP * 0.157) | round(1) }}"
                 device_class: "temperature"
                 unit_of_measurement: "°C"

[HotteX]

This works charmingly well.
I also added the switch, now the Sensor works as expected.

0x10:
      0x06:
         device_config:
            command: ""
            channel: ""
            log_learn: ""
         entities:
            - component: "sensor"
              name: "t_raw"
              config:
                 state_topic: ""
                 value_template: "{{ value_json.TMP }}"
                 device_class: "temperature"
                 unit_of_measurement: "°C"
                 enabled_by_default: "true"
            - component: "sensor"
              name: "tempC"
              config:
                 state_topic: ""
                 value_template: "{{ value_json.TMP | round(1) }}"
                 device_class: "temperature"
                 unit_of_measurement: "°C"
            - component: "sensor"
              name: "setpoint"
              config:
                 state_topic: ""
                 value_template: "{{ (value_json.SP * 0.157) | round(1) }}"
                 device_class: "temperature"
                 unit_of_measurement: "°C"
            - component: binary_sensor
              name: "Nightmode"
              config:
                 state_topic: ""
                 value_template: >-
                    {% if value_json.SLSW == 1 %}OFF{% else %}ON{% endif %}

Perfect !

So I will add the support for A5-10-06 based on your work. Thanks 👍
Just, as the idea is to be compatible with all devices, I must keep SP as raw data as the scaling seems to be device dependent.
Also, I will set t_raw as disable by default as tempC will be enough for 99.99% of users 😊
So you will have to keep your mapping.yaml file.

That makes me think that I have to better manage such cases. Because managing a separate mapping.yaml can be tricky while device support will grow.
I am thinking of adding a configuration option for devices, for example:

[my_eltako_A51006]
address = 0x01234567
rorg = 0xA5
func = 0x10
type = 0x06
scale = {"SP":0.157}

So that the scaling will be applied in a kind of an additional user-specific (or device-specific) processing layer to be defined.

[HotteX]

Indeed. I was not aware that the spec of the EEP does not specify a range or unit for the value.
Maybe its more universal to add the whole value_template string as an optional config ("SP":"(value_json.SP * 0.157) | round(1)") that falls back to default, when none is given? A bit more complicated, but more flexible for whatever shennanigans turn up in future.
And also the unit as an optional field for the Friends of Fahrenheit.

I can also confirm the integration of A5-04-01 and A5-04-02 (one of them is currently only in mapping.yaml, but not normally available so I guess it's untested) works fine.

[mak-gitdev]

Yes, that's another option. I will see which one is easier to use and easier to implement.

Thanks for your contribution 👍
