How can i use bitcoded sensor

Configuration
1

Hi
i have an modbus sensor:
- name: isg_betriebsstatus
input_type: input
address: 2500
slave: 1

the value of the sensor is bitcoded:

HK 1 PUMPE B0
HK 2 PUMPE B1
AUFHEIZPROGRAMM B2
NHZ STUFEN IN BETRIEB B3
WP IM HEIZBETRIEB B4
WP IM WARMWASSERBETRIEB B5
VERDICHTER IN BETRIEB B6
SOMMERBETRIEB AKTIV B7
KUEHLBETRIEB AKTIV B8
MIN. EINE IWS IM ABTAUBETRIEB B9
SILENTMODE 1 AKTIV B10
SILENTMODE 2 AKTIV (WP AUS) B11

for example i get a value of 81 = 01010001
which means bit 0 (HK 1 PUMPE ), bit 4(WP IM HEIZBETRIEB) and bit 6 (VERDICHTER IN BETRIEB ) are active

how can i show these values in homeassitant?

Hello everyone,
I’m struggeling with my bitcoded value from my LWZ.
In my isg_sensors.yaml I’ve got a sensor representing the systemstatus called “Betriebsstatus”

  - name:                'HEIZUNG-BETRIEBSSTATUS'
    slave:              1
    address:            2000
    input_type:         input
    data_type:          uint16

At present I got the value 17.

In a second file called binary_sensor.yaml I hava got separate sensors to get the different status out of the bitcoded value.

- platform: template
  sensors:

    isg_betriebsstatus_hk1_pumpe:
      friendly_name: "Heizung Schaltprogramm aktiv"
      value_template: "{{ states('sensor.HEIZUNG-BETRIEBSSTATUS')|int|bitwise_and(1) > 0 }}"
    
    isg_betriebsstatus_hk2_pumpe:
      friendly_name: "Heizung Verdichter"
      value_template: "{{ states('sensor.HEIZUNG-BETRIEBSSTATUS')|int|bitwise_and(2) > 0 }}"

      friendly_name: "ISG State Defrost active"
      value_template: "{{ states('sensor.HEIZUNG-BETRIEBSSTATUS')|int|bitwise_and(512) > 0 }}"

    isg_betriebsstatus_silentmode1_active:
      friendly_name: "ISG State Silentmode1 active"
      value_template: "{{ states('sensor.HEIZUNG-BETRIEBSSTATUS')|int|bitwise_and(1024) > 0 }}"

    isg_betriebsstatus_silentmode2_active:
      friendly_name: "ISG State Silentmode2 active"
      value_template: "{{ states('sensor.HEIZUNG-BETRIEBSSTATUS')|int|bitwise_and(2048) > 0 }}"

My dashboard shows for all binary sensors the vale “not availible”. I can not get it run.

Does anybode have an idea, where to find the mistake or waht to change?

exactly what i was looking for! Thank you very much! :slight_smile:
