I've been following the story for a while and it has never been adequately explained by mainstream media. Consider this... They drove for over an hour in the middle of the night in foul weather to a remote location to cut down a particular tree. That suggests some preplanning.
This is exactly what I want, but don't really want to run Docker all the time. Nicer git worktrees and isolation of code so I can run multiple agents. It even has the setup command stuff so "npm install" runs automatically.
I'll check this out for sure! I just wish it used bubblewrap or the macos equivalent instead of reaching for containers.
I have also been enjoying having an IDE open so I can interact with the agents as they're working, and not just "fire and forget" and check back in a while. I've only been experimenting with this for a couple of days though, so maybe I'm just not trusting enough of it yet.
Sample size of 1, but I have a friend who does buy the refills and charges the original unit. Every shop that sells the combination units also seems to sell the refills (at least around here).
> The batteries can fill up on the off-peak rate overnight at £0.07/kWh, and then export it during the peak rate for £0.15/kWh, meaning any excess solar production or battery capacity can be exported for a reasonable amount.
Honestly I didn't know this was allowed.
I recently got a heat pump and am on a time-of-use tariff (https://octopus.energy/smart/cosy-octopus/) and have been thinking about pulling the plug on battery storage for a similar purpose (charge during the cheap hours; run the house off battery during the day). I am currently using between 40-50kWh per day - anyone have similar usage to this and can recommend batteries for this?
A word of caution:
It's worth factoring in battery depreciation. That 7p→15p arbitrage isn’t "free" profit: you pay round-trip losses and you burn cycle life. If you assume ~£X installed, ~Y usable kWh, ~Z cycles to 70–80% capacity, the wear cost alone is often several pence per kWh throughput, which can wipe out most of the spread.
The only restriction placed on you is the export rate, which is provided to you by the DNO here in the UK. We had a limit of 3.8kW placed, which is programmed in to the batteries by the installer.
I just had Solaredge battery installed in my house in the UK (Had a solaredge PV and inverter so made sense even tho it was more than other setups). If you are up for a challenge https://springfall2008.github.io/batpred/ is AMAZING and basically optimises when to charge and discharge your battery.
I've got a heat pump and think my paypack period is going to be about 6 years.
Hit me up on bluesky (in profile) if you want more info!
Yeah not sure really. I thought these time of use tariffs were intended for charging EVs and using heat pumps, not charging batteries and selling the energy straight back to them later on in the day. But when you put it like that (decentralised grid storage) I guess it makes sense.
It benefits the grid to have people consume extra power when there's an oversupply, store it and give it back when there's undersupply. Why shouldn't it be allowed (even encouraged)?
I'm definitely coming round on the idea of a heat pump. My house was built in 2002 and still has the original gas boiler that was installed from then. I'm hopeful that I have enough insulation, but I've been told I may have microbore piping which might need to be upgraded. Not done much more research on it than that.
Also apparently my gas boiler has an air brick that's too close to the output for the boiler on the outside of the house, so they'd have to install a bigger flue that goes halfway up the house.
From what I've heard the installation cost (even with £10k subsidy) will still be minimum £5k compared to a new gas boiler of £2.5-3k.
After everything that's happened with the gas prices in the past 3 years, I'm very eager to remove that dependency from my house. Now we just need to decouple the gas prices from the renewable energy prices so we can start to see those lower prices to the home. One can dream.
I use Tailscale for a bunch of self hosted services on a raspberry pi in my house. Port numbers and TLS certs are my current main problems with this setup but it's not annoyed me quite enough yet to do anything about it.
BTW why bother with TLS over already-encrypted and authenticated Wireguard tunnels? Is this just so that browsers won't complain, or do you have a more complex threat model?
Sorry for late reply, exactly that yeah - so the browser doesn't complain. I'm not worried about the security of HTTP over wireguard or anything like that. And domain names are easier to remember than ports so... http://raspberrypi:8123/ vs homeassistant.raspberrypi.local (or something)
> I use Tailscale...Port numbers and TLS certs are my current main problems with this setup
I've been running a Tailscale container, using the `tailscale serve` feature[0], as a sidecar for each containerized service I want to access. External access, TLS (to make my browser happy), and domain names all come for almost free. This allows me to set up `https://my-cool-service.lemur-pangolin.ts.net` with relative ease.
There's a ton of boilerplate, which drives me a bit nuts. But at least copy/paste is easy to do. Looking just now I have 31 Tailscale containers running that are almost duplicates of each other. You could probably do config generation but for a homelab I'm not motivated to really do that.
The command line interface for this tool is a little bit limited and forces you to share the network stack between your service and the sidecar. I would recommend injecting a config file into each container to give you full flexibility. I put up an example config on pastebin[1].
Lots of options to proxy and provide automation for certs. I'm personally a huge fan of Traefik, but I know a lot of folks use NPM since it's so simple and Nginx has great performance overall.
I'm not sure that's true about the UK and prescription glasses. When I moved back here I packed my glasses up in storage so was going to be without for 6/8 weeks before our stuff arrived. I went onto Glasses Direct[1] and ordered 2 new pairs of glasses for £50 by putting in my prescription details from another country. The glasses themselves are regulated as medical equipment, but you could go on there and buy any prescription you want and nothing will stop you.
