RM3500WF detected as a switch but there is no sensor to track temperatures

[tessierp]

Hi,

I recently installed Neviweb130, works fantastically well with Sinope thermostats I have. Amazingly well done!

Recently I installed a water tank controller, RM3500WF. A switch was detected by Home Assistant to turn it on and off however there doesn't seem to be any support in Neviweb130 to keep track of the temperature sensor. Any idea why?

The RM3500WF is fully supported in neviweb130. The water temperature is reported as attribute water_temperature You just need to create a template sensor to track that attribute

template:
  - sensor:
      - name: "temperature_eau"
        unique_id: sensor.temperature_eau
        unit_of_measurement: '°C'
        device_class: temperature
        state_class: measurement
        state: "{{ state_attr('switch.neviweb130_switch_calypso_chauffe_eau', 'water_temperature') }}"

replace the last line by the name of your device. Should work without problem. You can check your device attributes in dev tools, states. Search for your device name switch.neviweb130_switch_name_of_your_device

The name of the sensor in my case is switch.neviweb130_switch_rm3500wf. I added the following :

` ########################

Water Tank Temperature

########################

• name: "water_tank_temperature" unique_id: sensor.water_tank_temperature unit_of_measurement: '°C' device_class: temperature state_class: measurement state: "{{ state_attr('switch.neviweb130_switch_rm3500wf', 'water_tank_temperature') }}"`

Didn't get any errors and I'm able to interrogate the sensor but it says the temperature is "unknown". I checked in the Neviweb app and I can see it is at 48C right now. I guess I will receive date the next time the temperatures changes and an event is triggered? (is it event driven or pull driven??)

The attribute name is «water_temperature». You put «water_tank_temperature» change the line for state: "{{ state_attr('switch.neviweb130_switch_rm3500wf', 'water_temperature') }}" «water_tank_temperature» is the name of your sensor

Ahh yes I changed that by mistake. Works now. Thank you!
