Solar PV Monitoring/Automation Thread

I just do max export allowed, and fix an SOC threshold for every hour.

So imaybe 20% per hour @ 5kW. So stop discharging when you hit 20% between 1 and 2, stop when you hit 40% between 12 and 1 etc......

You will finish each night at 20% SOC irrespective of the starting position

I do 15% per hour. It finishes early (reaches the low threshold) so reverts to discharging normally for the last 15 mins or so of each hour.

So you might end up actually hitting 9% that way, so you could set the threshold for 1 to 2 at 12%

So basically, Trigger time between 1:00 and 2:00 If SOC% > bottom level Then Dump Discharge Else Normal Discharge

Then repeat for all hours from 21:00

I'd be the same. Every 10 secs on a Gen 1 Hub, with a v5 Eddi and Zappi. No issues as far as I can see

Hi guys.

Ok so have been setting up my solar installation etc in HA (currently using Solis API data) but am pleased with how far I have come… I'll have load of questions on setting up the local data collection, currently reading up and looking at what is needed to get the data from the logger to HA.

In the mean time I've added all the Tuya devices I have dotted around the house to HA but am struggling with a couple of things?

Have a 30Amp switch on the immersion which integrates fine into HA except it doesn't give a running total of the power used, daily, monthly only power I can see is when it is in use and in the history graph.

On the Tuya APP running totals are shown, current, daily and monthly.

I've managed to extract the .Json data for the switch on HA, but thats about it.

The state is the only total I see and its not changed since the integration.

disabled": false,
"disabled_by": null,
"entity_category": null,
"device_class": null,
"original_device_class": "energy",

},

"last_updated": "2024-08-13T15:42:24.685852+00:00"

Question, can the "code" be changed to display the correct running total, if so how or is it a non runner?

Thanks

looking to do same with SOlis invertor to feed into HA

Did you create the defined time periods and names in automations.yaml? The example below is for a day/night meter (peak and offpeak), I don't see a reason why it can't have three periods.

- id: '1634335289003'
  alias: ESB Meter Electricty Meter Tariffs
  description: Day and Night PEAK Tariffs
  trigger:
  - platform: time
    at: 08:11:00
    variables:
      tariff: peak
  - platform: time
    at: '23:11:00'
    variables:
      tariff: offpeak
  action:
  - service: select.select_option
    target:
      entity_id: select.hourly_energy
    data:
      option: '{{ tariff }}'
  - service: select.select_option
    target:
      entity_id: select.daily_energy
    data:
      option: '{{ tariff }}'
  - service: select.select_option
    target:
      entity_id: select.monthly_energy
    data:
      option: '{{ tariff }}'

Then create utility_meter in configuration.yaml:

utility_meter:
  hourly_energy:
    source: sensor.shelly_em_esb_meter_channel_1_energy
    name: ESB Meter Hourly Electrical Energy
    cycle: hourly
    tariffs:
      - peak
      - offpeak
  daily_energy:
    source: sensor.shelly_em_esb_meter_channel_1_energy
    name: ESB Meter Daily Electrical Energy
    cycle: daily
    tariffs:
      - peak
      - offpeak

And then a pricing template in the same file:

template:
  - sensor:
      - name: "Hourly Cost Total Peak"
        unique_id: "template_sensor_4"
        device_class: monetary
        unit_of_measurement: "€"
        icon: mdi:currency-eur
        state: >
          {{ (states('sensor.hourly_energy_peak') | float * 0.3648 ) | round(2) }}

      - name: "Hourly Cost Total Off Peak"
        unique_id: "template_sensor_5"
        device_class: monetary
        unit_of_measurement: "€"
        icon: mdi:currency-eur
        state: >
          {{ (states('sensor.hourly_energy_offpeak') | float * 0.105) | round(2) }}

Some of the cards on my energy dashboard.

@Latro , how are you calculating your heatpump COP?

Is it possible to run both ha-solarman and home_assistant_solarman together so I can test if the new fork is going to work for me?

I haven't updated anything on the original since v1.4.3 for fear I'd brick something.

Presumably, there are commonalities between the two and so installing ha-solarman might overwrite on top of home_assistant_solarman?

On the energy dashboard in HA.

Is there a way to get a figure for self consumed solar?

I know I can hover over the bars to get it but I'd like to see it "live".

thanks
