So, my run of 6+ months o no LS in my area came to an abrupt end yesterday. We're shedding per the schedule again.

Neighbours are not happy - I wanted to tell them "Welcome to the rest of RSA - they've been suffering - now its our turn"

Thankful for solar and batteries.

Yeah probably due to stage 6

Nah, we've had plenty of stage 6 over last 7 months. Even then, nothing happened.

But many of areas got moved to new "block" So I think we were moved too - hence the LS kicked up again.

Eskom caught lying again

Eskom’s coal-fired power station breakdown lie

Eskom’s latest energy availability factor (EAF) data reveals that the power utility has been misleading South Africans about the true reasons for breakdowns and load-shedding.

Not actually caught. Eskom have given various reasons including poor management as the cause of load shedding and age would be one of those factors. The article is misleading.

Well in SA we get power from fossilized dino farts so makes no diff.

In fact its more efficient cause it doesn't double+ convert:
Gas = Heat -> room
Power = Heat -> turbine -> transmission -> V conversion -> heat -> room.

I really should get one of those dino fart burners, with the right gas canister.

LS stopped in our area on 5th April.
Seems there is a stuck relay at the substation.
CityPower has planned maintenance on Sun 16th to fix the stuck relay.

Below grafana chart is from inverter's data saved into a database every minute.
Grid feed Hertz/Volts when they are zero.

Also thankful I have solar and batteries.

Would you mind sharing how you set that graph up? All my Inverter data goes to Grafana too - and uses influx as DB.

Just don't buy the canister via Takealot. They sell empty ones!! :D

For the same price of Takealot, you can buy new + filled at the local gas depo. Well, I could.
Wasted my time buying from Takealot and driving to the gas depo to fill where they sold exact same brand and fill it for you.

Chart type Table
Show Table Footer On, Total (select the fields)
Override Field -> Cell Option -> Cell Type Gauge

I have a daily summary table "solar_assistant_day"

SQL: 
SELECT
   TO_CHAR(dt, 'Dy DD Mon') as "Period",
   load_energy as "Load out",
   grid_energy_in as "Grid in",
   self_energy as "Self_kWh",
   pv_energy as "Solar PV",
   load_energy*tariff as "R Load",
   grid_energy_in*tariff as "R Grid",
   self_energy*tariff as "R Saved",
   self_energy/load_energy * 100 as "Ratio",
   EXTRACT(epoch FROM grid_time_off)/60 as "Load Shedding",
   grid_cycles_off as "LS Events"
FROM solar_assistant_day
LEFT OUTER JOIN city_power_tariff ON date_trunc('month',solar_assistant_day.dt) = city_power_tariff.year_month
WHERE $__timeFilter(dt)
ORDER by dt desc
The full chart is attached
