In light of the new wind generation record on the Irish grid over the weekend, I figured this might of use to some people here. Home Assistant rest sensor config to pull stats from the Eirgrid dashboard.
rest: - resource: http://smartgriddashboard.eirgrid.com/DashboardService.svc/stats?area=CO2Stats®ion=ALL scan_interval: 900 sensor: - name: "eirgrid_co2_intensity" value_template: "{{ (value_json.Rows | selectattr('FieldName','eq','LATEST_INTENSITY') | list | first).Value }}" unit_of_measurement: gCO2eq/kWh - resource: http://smartgriddashboard.eirgrid.com/DashboardService.svc/stats?area=WindStats®ion=ALL scan_interval: 900 sensor: - name: "eirgrid_latest_wind_generation" value_template: "{{ (value_json.Rows | selectattr('FieldName','eq','LATEST_WIND_GENERATION') | list | first).Value }}" unit_of_measurement: MW - name: "eirgrid_forecast_peak_wind_generation" value_template: "{{ (value_json.Rows | selectattr('FieldName','eq','FORECAST_PEAK_TODAY') | list | first).EffectiveTime }}" - resource: http://smartgriddashboard.eirgrid.com/DashboardService.svc/stats?area=FrequencyStats®ion=ALL scan_interval: 900 sensor: - name: "eirgrid_grid_frequency" value_template: "{{ (value_json.Rows | selectattr('FieldName','eq','LATEST_FREQUENCY') | list | first).Value | round(2) }}" unit_of_measurement: Hz - resource: http://smartgriddashboard.eirgrid.com/DashboardService.svc/stats?area=GenerationStats®ion=ALL scan_interval: 900 sensor: - name: "eirgrid_latest_generation" value_template: "{{ (value_json.Rows | selectattr('FieldName','eq','LATEST_GENERATION') | list | first).Value }}" unit_of_measurement: MW - name: "eirgrid_net_import_pct" value_template: "{{ (value_json.Rows | selectattr('FieldName','eq','NET_IMPORT_PCT') | list | first).Value | round(2) }}" unit_of_measurement: "%" - name: "eirgrid_renewable_generation_pct" value_template: "{{ (value_json.Rows | selectattr('FieldName','eq','RENEWABLE_GENERATION_PCT') | list | first).Value | round(2) }}" unit_of_measurement: "%" - name: "eirgrid_thermal_generation_pct" value_template: "{{ (value_json.Rows | selectattr('FieldName','eq','THERMAL_GENERATION_PCT') | list | first).Value | round(2) }}" unit_of_measurement: "%"
The CO2 intensity figure is particularly useful for automating loads to run at the greenest time.

Got my two extra ShellyEMs set up this morning so I am now logging 6 channels in my main consumer unit. Shelly sent me an extra one by mistake...
Circuits I logging at the moment are; Main ESB Incomer (to see if I am exporting), Heat Pump, Utility Rooms sockets, Solar PV, Kitchen ovens and my TV room. Probably might shift around the CTs over the coming months to different circuits so get a full breakdown of my energy consumption.
For a comparison see the graph below which is the HACS Solarman Web scraper in Home Assistant and the Shelly logger. This was the primary reason I got the extra ShellyEM as you can see the frequency of the readings there is no comparison....

Looking for some help finding the Solis modbus registers for the details below as I would like to stop pulling from the cloud and hit the inverter directly.
I have gone through that pdf but I either can't find them or they called something odd.
I am bringing all of these values in from Solis cloud so they exist there (but maybe not on the inverter?)
Also, is there any way to read the 12xxx registers? pysolarmanv5 fails when trying to read those, need it for Grid Status which is 12590, and a few others.

Yeah they're not there for this month/this year it seems:
Unless they could be somewhere still since this list is quite old at this stage. Would be nice to have an official one from Solis.
And thanks for the correction, that works, I didn't realize they use a different method than the rest.
Also is there a way to pass an array of non-sequential registers to the method instead of calling it multiple times with different registers? I know you can give it a range but that would also grab not needed data.
