I am pretty deep into HomeAssistant. Have many Sonoff and Shelly devices throughout my home, including light switches, breakers, temperature monitoring etc. The possibilities are almost endless - I have many automations which run my home, from consuming forecasts from Solcast to determine what should run and when it should run based on solar predictions. Automation of lights based on alarm triggers, camera automation to tell me when a vehicle or person arrives at my gate. Notifications if gates or garage doors are left open. Gas consumption and remaining gas monitoring. Automation of lights using sunset / sunrise. Adjusting of battery charge based on load shedding schedule ensuring that my batteries are full prior to load shedding starting. Its a rabbit hole, once you understand the concepts its extremely powerful. Homeassistant has matured significantly over the past ~ 2 years, although updates can be painful at times it's been fun. I have some Tuya devices (Geyser Wise) which I run TuyaLocal for - I prefer local for all connectivity. What inverter do you have? Happy to try answer any questions you may have.

Friend of mine, on solar assistant since May. 1 Household.

Unfortunately not, ended up chatting with Freedom Won, they updated the batteries firmware, couldn't test though as the batteries were already full. Big props to Freedom Won for their support. It was lighting fast and the gent that helped me was knowledgeable. I initially logged it with Sunsynk, the agent logged in, he changed all my SOC to 90% and enabled grid charge for all slots then told me it's "fixed"... 🤦‍♂️ I also changed my aux back to an output as I had it as a gen input, either that resolved the issue or the battery firmware upgrade fixed it. Rock solid again 😃

Absolutely, sweet deals all round

Interesting that there is no LS in Namibia even though 60% of your power is provided from SA and purchased from Eskom/SAPP😅 Agree with recommendations above, Deye/Sunsynk no batteries and the grid as shortfall.

Specs: Sunsynk 8kW - FW M 6.0.2.4 / S 1.7.2.4 / C E.4.3.0 Battery: 2x Freedom Won eTower 5kWh. Seem to have a strange issue that I haven't observed before, my inverter is bouncing between charging and discharging when getting to the SOC set on my timer. Recording of it doing this below. Any idea on why this may happens? Timer Settings:

I can check when I'm home. I would estimate about 2 meters each. I see that people have purchased the plugs and made up their own cables if they are too short. Edit : 60cm per cable

This article is so wishy-washy. Sounds like a butt-hurt supplier who's sitting with stock.

Its possible yes, but it doesn't just take the surplus. Lots of people use automations to get solar forecasts (solcast) for the day or remaining based on hour, combined with battery SOC, Load etc and determine when to run their geysers. Check out Home Assistant I currently run mine with a more manual approach as I cannot specifically define my approach yet. For now - I have a dashboard which gives me the solar forecast for the next 7 days. Usually check this in the morning to prioritize what's run at home. 95% of the time it's accurate within 1kWh. I then turn on/off throughout the day.

Been meaning to do something similar for some time, like the approach of going to Postgres first. What do you use to display these as sensors in HA? The frequency of 1 minute, is this just to reduce writes and storage requirements in the long term? Gotten use to having SA "realtime" in HA.

Love the stats, willing to share some of your config for these 🥺

You shouldn't need to convert to kWh it should already Heres mine for PV_Today (Important to make sure your timezone and date/time are set as well!) Here's load -

@Deondup Yes have it all working - You need to use utility meters, Under Settings > Device & Services > Helpers Click Create "New Helper" > Select Utility Meter Can then define the period - ensure you leave "Periodic Resetting" Enabled. Let me know if you don't come right.

If I turn off the fence, the tripping stops, so it is the fence, I could hear it shorting to the stay. Thought it was potentially one of the wall lights has a neutral that was touching either the wall, or the mounting point - which was getting a little current back and causing the earth leakage to trip. Hard to determine though. There are a lot of lights and they are daisy-chained along the wall.

Hi All, So I have a weird new issue - yesterday a branch fell onto my electric fence at my front gate which caused one of the wires to move from the bobbin, causing a short to the stay. The fence remained on, however my earth leakage tripped in the main DB and continued to trip. I only figured out later that it was the fence that was causing the trip. The only way I can see this happening is through the gate DB board (which is plastic). The gate DB has 3 breakers - 1x 32 A main breaker, 1x16A gate breaker and 1x16A breaker for the wall lights. The conduit does run along side the electric fence, although its plastic. Any ideas?

Also running this - no change from what I can see. Anybody get a response from support?

Always fun seeing a slate install. What's your preference for securing the cabling to the panels/roof in this case?

Thanks @Steve87 makes sense. Interesting concept, would be interested to find out if anybody has done this successfully.

Hi all, Looking for some input/advice here on how best to work around this - I have a 3 phase Sunsynk inverter which provides all my power 99.7% of the year, I very very rarely use any utility power whatsoever. My connection fee for 3 phases is very expensive - I have the option to reduce to a single phase 63amp supply and save around R60k per year. I do have 3 phase aircons, but these are not essential and do not need run when the grid is the only input. If I made the move to a single phase - A ) Still be able to provide a single phase input to my inverter to provide power in the unlikely event that I need the grid (I understand I am limited to the 63 amp supply and it'll only be for a single phase) B ) Still be able to output 3 phases from my inverter to avoid me having to rewire my board - also due to aircons being 3 phase

@slipx any plan to have daily totals for aux outputs? I have split mine out with the aux options you added - but would love to have them display their usage for the day.

Thats okay! You just replace control board in the geyser wise, just make sure you get the same model. For the meantime that would allow you control your geyser just using Tuya for now. https://plumbitonline.co.za/product/geyserwise-tse1-pcb-for-tuya-smart-wifi-retrofit-pcb-only?gad=1&gclid=Cj0KCQjw2qKmBhCfARIsAFy8buI14s3Q1mJzSH36Gap0cPx4J2GY9LFRTxPy7xrznLXSjqC_ZTg11nsaAor7EALw_wcB

If you have home assistant already and a Tuya geyserwise, you can already do this with a simple automation. I use the loadshedding integration from WernerHP, it uses the ESP API, I don't use timers though, I just check the current temp, and adjust based on what I need. Busy adapting to use Solcast in order to heat during the best solar hours for that day.

Trying to get information on net metering within South Africa - specifically, Johannesburg, has anybody managed to apply? Keen to purchase more panels - but want to know if I should go all the way for the benefit of net metering in the long term.

Do you have an agreement in place your electricity provider to export? If you do, then yes Import-Export = Net Usage. If not you are legally not allowed to export electricity at all, and depending on your meter - you may actually get billed for the export...

I have a Shelly 3em, very happy with it, native integration to HA, and seems pretty accurate.
