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


==== 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 [[https://hass.telavivmakers.space|HomeAssistant]] "cloud" machine


==== mqtt ====

push it to over mqtt, using 

<code>
 sudo rtl_433 -F "mqtt://10.81.2.3:1883,user=tami,pass=tamispace"
</code>
using service
<code>
yair@telavivmakers:~$ sudo systemctl restart rtl433.service
</code>

==== hass ====

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 ''root@telavivmakers:/home/yunohost.app/homeassistant/configuration.yaml'' \\
and reload the yaml (''Developer Tools/yaml'')
test new yaml in (''Developer Tools/template'')
<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() }}"
</code>

to sum the three meters and convert to Kw. add
<code yaml>
sensor:
  - platform: template
    sensors:
      cc_power_total:
        friendly_name: "Energy (total)"
        unit_of_measurement: 'W'
        device_class: power
        value_template: "{{ states('sensor.cc_power0') |float + states('sensor.cc_power1')|float + states('sensor.cc_power2') | float }}"
    
  - platform: integration
    source: sensor.cc_power_total
    name: energy_spent
    unit_prefix: k
    round: 2
</code>

reload yaml \\
then add ''energy_spent'' to ''config/energy'' as ''Grid consumption''
