Is "set and forget" a realistic possibility?

I have said elsewhere that my aim is to set up my inverter so that it does not require continuous tweaking. I know that this may be naive, but how does it look so far?

Well, I think that the Octopus Cosy tariff makes all the difference. Without the afternoon cheap rate period, I don't think that it would be possible to adjust the inverter in such a way that it would work well on sunny and overcast days alike. Reading the forums, it looks like some people have set up quite elaborate automation to take advantage of weather reports, published tariff changes, etc. This is not something that I particularly want to get into.

The Octopus Cosy tariff seems to work very well for me. On sunny days, despite setting "Priority Load", my batteries are reasonably full by the time 1pm rolls around. This means that the automatic charge from the grid is minimal. I am experimenting with splitting the 1pm-4pm cheap rate period into two (or even three) segments with different SoC targets. When I have refined my strategy a bit more I will post some representative graphs here.

UPDATE: Since I wrote this I have switched from Octopus Cosy to Octopus Agile. My strategy is basically the same as when I was on Cosy, but the prices are lower. I am trying to be aware of my relative cost on different tariffs. The Octopus Compare app makes that easy to do.

Automation tasks underway

I have the following automation tasks underway, in various stages of completion: If there is a suitably inexpensive timeslot overnight, use it to top up the batteries to 100%. Using this, instead of solar, will allow more solar to be exported at 15p/kWh. Inexpensive slots during sunlight hours are not as useful because I can't export at the same time as using electricity from the grid. If there is not a suitably inexpensive timeslot overnight, top up the batteries from the grid during the period coming up to peak time (which is usually fairly reasonably priced). Make sure any battery charging from the grid is definitely off before the 4pm-7pm peak rate starts. When the electricity price goes negative, boost the hot water temperature using the heat pump and immersion heater. This is a way of benefitting from being PAID to use electricity and storing a little of it in the form of hot water. Change the colour of a lamp in the kitchen to reflect the current electricity

No, YAML ain't, but what is it?

YAML is said to stand for "YAML Ain't a Markup Language". This unhelpful acronym (and brazen use of the old "GNU = GNU is Not Unix" joke) doesn't really help in understanding YAML as it pertains to Home Assistant. Well, in this context, YAML is a way of defining the hierarchical configuration settings that drive Home Assistant. So, suppose we have some settings such as: Lights: Left: Brightness: 4 Colour: "Red" Right: Brightness: 6 Colour: "Green" Fans: Extractor: 2 YAML is just the thing to define such a hierarchical structure. For the moment, don't worry too much what these might represent. Consider, however, that we might want the actual settings (such as 4 or "Red") to be controlled by some variable quantity derived from something else within the system. In this case it would be useful to be able to replace the settings with snippets of Python code. And this is, effectively, what H

A new strategy, a new approach to automation

As I explained before, I was very wary of automating my system beyond what the inverter could do natively. As a retired elecronics and software engineer there is too much danger that such an endeavour would become a slippery slope. Well, I now have one foot on that slope! What prompted this change of heart? Well, during the last month we had some periods with VERY low Agile prices and it got me thinking about how I use my generated solar power. One way of looking at it is to look at the "opportunity cost" of the solar power generated. The incoming solar power, thanks to the sunk cost of the system, comes in at 0p/kWh. However, I can sell any excess back to Octopus at 15p/kWh. That means that, effectively, any solar that I use is costing me 15p/kWh - inasmuch as I could sell it if I want to. This way of thinking leads me to consider a different strategy: What if I were to charge my batteries on a cheap rate at night and, during the day, export most or all of my solar at 15
