====== Electrical current sensor  ======
<del>https://hass.telavivmakers.space/dashboard-energy/0</del>

==== TODO: ====
  * finish mqtt integration 
  * sum the three current sensors to one [[https://community.home-assistant.io/t/172779|link]]
  * kill all our consumers and calculate the base (we share power with upstairs)
  * remove (or integrate to ) the default energy tab
  * integrate ''$/hour'' to the page

==== what we haz ====
our current sensor is clamped onto our three main arteries
and is streamed using [[https://github.com/merbanan/rtl_433|rtl_433]] \\
running on the devdesk pc (on electric bench) to the [[https://hass.telavivmakers.space/dashboard-energy/0|energy tab]] of tami's [[https://hass.telavivmakers.space|HomeAssistant]] (a.k.a hass) .


==== mqtt ====

push it to over mqtt, using 

<WRAP center round important 60%>TODO: make this systemd service, currently running on tmux using byobu</WRAP>
<WRAP center round important 60%>need remote access, send your tailscale</WRAP>

<code>
devdesk@10.81.2.121:~$ rtl_433 | tee >(mosquitto_pub -h 10.81.2.3 -u tami -P tamispace -t rtl_433 -l) 

</code>


==== hass ====
<WRAP center round important 60%>TODO: re-implement</WRAP>

and from there to the homeassistant 

in hass, as our sensor does not conform to the standard ''power_w'' expected output.  \\
a solution [[https://github.com/pbkhrv/rtl_433-hass-addons/issues/101#issuecomment-1190281549|was found]], and integrated to hass [[https://www.home-assistant.io/docs/configuration/|configuration.yaml]]

**tl;dr**
add the following to the ''config/configuration.yaml'' \\
and reload the yaml (''Developer Tools/yaml'')
<code yaml>
mqtt:
  sensor:
    - name: cc_power0
      state_topic: rtl_433/74930c0d-rtl433/devices/CurrentCost-TX/3202/power0_W
      device_class: power
      unit_of_measurement: W
      state_class: measurement
      value_template: "{{ value | round() }}"

    - name: cc_power1
      state_topic: rtl_433/74930c0d-rtl433/devices/CurrentCost-TX/3202/power1_W
      device_class: power
      unit_of_measurement: W
      state_class: measurement
      value_template: "{{ value | round() }}"

    - name: cc_power2
      state_topic: rtl_433/74930c0d-rtl433/devices/CurrentCost-TX/3202/power2_W
      device_class: power
      unit_of_measurement: W
      state_class: measurement
      value_template: "{{ value | round() }}"
