The Snektek Solar Dashboard can be used as a sensor entity on Home Assistant.

Add this to your configuration.yaml:

Code: Select all

This code works great! thanks Jonathan!!!

here is code in my home assistant dashboard for gauges. You would need to adjust severity values to fit your solar system but gives you an idea of display in HA I have a renogy controller so the Total moth and year sadly dont work.

Code: Select all

type: grid
cards:
  - type: gauge
    entity: sensor.solar_voltage
    min: 0
    max: 54.16
    name: PV Volts
    needle: true
    severity:
      green: 25
      yellow: 7
      red: 0
  - type: gauge
    entity: sensor.solar_current
    min: 0
    max: 20.32
    name: PV Amps
    needle: true
    severity:
      green: 10.16
      yellow: 5
      red: 0
  - type: gauge
    entity: sensor.solar_power
    min: 0
    max: 480
    needle: true
    severity:
      green: 260
      yellow: 115
      red: 1
    name: PV Watts
  - type: gauge
    max: 14.4
    entity: sensor.battery_voltage
    needle: true
    name: Battery Voltage
    severity:
      green: 13
      yellow: 12.5
      red: 10
    min: 12
  - type: gauge
    entity: sensor.solar_generation_today
    min: 0
    max: 2
    name: Today
    needle: true
  - type: gauge
    entity: sensor.battery_current
    needle: true
    min: 0
    max: 50
    severity:
      green: 10
      yellow: 20
      red: 45
  - type: gauge
    entity: sensor.solar_generation_this_month
  - type: gauge
    entity: sensor.solar_generation_this_year
columns: 3
square: false

Thanks for posting the gauges code I edited your post for formatting

Hi there is within /cur_data several items not used in the example from Jonathon. But I believe they are Maximums from Panel, Battery and Load. Then some I haven't a Idea to there meaning. I was looking for description of the variable names. "pv.v.m":37.3,"pv.c.m":3.36,"pv.p.m":106,"bt.v.m":14.2,"bt.c.m":7.35,"bt.t.m":47,"eq.t.m":50,"ld.c.m":6.58,"ld.v.m":14.2,"ld.p.m":93,"pv.v.mi":19.8,"pv.c.mi":0.64,"pv.p.mi":24,"bt.v.mi":13.1,"bt.c.mi":1.67,"bt.t.mi":46,"eq.t.mi":49,"ld.c.mi":5.66,"ld.v.mi":13.1,"ld.p.mi":74,"

Hi Tom,
.m is maximum since restart
.mi is minimum since restart.

Perfect Thanks
