Roof assessor came this week. Cracks in the skylights were taped up and made waterproof. One of 16 solar panels was shattered.
That along with the recent discussions about solar motivated me to finally sort out my own solar system that I inherited two years ago. After far too much stuffing around I got my Goodwe GW5K-DT inverter hooked up to Home Assistant. As @Belfry has power monitors on all his appliances I grabbed an extra six pack of Meross plugs and did the same. That covers the servers, router, workstation, TV, refrigerator, dishwasher and washing machine.
Sorting out the grid was more difficult. I had to cut off the Energex lock on the meter to see what was going on and I am told a new one will cost me about $100 to replace. 
However, once in, I found the system was installed in 2021, so it’s not that old. The meter has a digital display but there is no blinking light to monitor consumption as @jdownie is doing.
Origin Energy will give you your past consumption and feed in, in hourly segments. There is no API but you can download a CSV file which has 2 years worth of data in my case.
In home assistant you can create a REST interface for these variables and pipe the data into home assistant for display and hopefully correlate it with the inverter data. I made some progress with this but debugging it is a daytime operation. For a string inverter no sun means it shuts down. If others have succeeded in getting this to work with this I would be interested to hear.
The better solution might be to have a supplier that has an API and can give almost instantaneous usage and spot price data. Amber Energy has this but there be dragons.
All this made me wonder whether I should get a new battery system. Goodwe has its new ESA system that looked pretty neat but there is lots of other “fun” stuff out there. Most of it is confusing to the end user and the recommendations date pretty quickly. I thought Finn Peacock from Solar Quotes gave a good overview. He is an entertaining speaker and presenter.
I had used his site, Solar Quotes, previously when buying my first solar system. His recommended installer was on the Gold Coast and did a good job but once they were done they were gone. The requisite inspection a few months later found a few defects that needed to be fixed but by that time the company had gone bust and there was no one to do the repairs. @Belfry reports this is not an uncommon experience.
Finn gives a plug for Solar Quotes at the end of his review and promises “I literally guarantee you will get a good install when you use our service.”
I guess everybody is ultimately a salesman.
