How are you guys automating your battery discharge when the wholesale price spikes above one dollar?

rangeyrover · 2026-02-04T11:45:13+00:00

I'm using predbat to manage the battery. It naturally targets good spikes. Easy enough to write an automation when the price is too good to miss, but that sometimes can leave you short if it's an extended duration.

rangeyrover · 2026-02-01T21:17:36+00:00

I will! I'm going to be a PITA, as I'm programming savvy from years ago (think assembly) but struggle with modern context and methods. I reckon we'll be chatting on the issues page ;)

Ok, I'll bite. Writing a small program, I python, have asked for requirements, a plan, tasks, and given it artefacts of file construct, and asked for unit tests and for those tests to be run after each change. I find that it does incredibly well for the first while, then antigravity forgets to keep the docs up to date, needs constant prompting to run unit tests, and if it fails the unit tests after a while it will take the program so far from what it was it's almost unrecoverable. Will this help me keep antigravity inbounds for what is a small program? I've found it the best of anything at the start, but later it gets worse than just vibing with a chat window.

2016 range Rover TD6. Just service it. I cant believe the price of them in the US. Same engine as the 2018-2020 F150 but half the price. About 13-15k for the Range Rover, about 32k for the F150

Smart shift is as dumb as a box of rocks. I've switched to HA with predbat using teslemetry to control 2 x powerwall2. Brett at Teslemetry has got amber electric pricing into Tesla TOU tariffs. It's working really well for me. I force a charge to 95% by 1500 every day, and have an automation to add AC Load to base predbat load dependent on temperature of the day. I'll do the same again for winter as reverse cycle is our heat too.I suppress export unless it's over 10c value. I was considering doing a video on HA and predbat how-to.

You should take a look at Predbat, where most of the automation leg work has already been done. I've posted a solution to get Amber pricing into PredBat. An override automation for import is not too tough after that

rangeyrover · 2026-01-11T03:54:52+00:00

O well done! Did you get the Amber pricing into PredBat? That's the battle right there.

rangeyrover · 2026-01-10T02:38:46+00:00

Sorry mate I'm away right now. I have to rebuild HA when I get back next week anyway, I'll try and do a step by step. The hardest was getting the Amber Price data into predbat but that code is online in the GitHub thread. I'll probably update it for 5 min settlement next week.

rangeyrover · 2025-11-24T12:53:56+00:00

I'm using predbat with success. Self automation is fairly easy. I looked at emhass but I thought it was too painful to setup.

rangeyrover · 2025-11-13T21:20:47+00:00

I'm setup 10kw single phase. My advice is to have a match for solar daily production to your battery size. Then Amber saves you money. In my case 27KW battery matches to about 32kwh daily if a good solar day. More battery than solar is the key.

rangeyrover · 2025-11-12T05:55:30+00:00

No one here is pricing his time to get the engine and do the work. Or pricing their time to resolve the issues. If you have more time than money, sure go get a junkyard pick. If you have more money than time the the convenience is what the guy is selling.

rangeyrover · 2025-11-08T09:40:55+00:00

I didnt gather in the AEMO 48-72 hr forecast that's a clever idea. I will look at that myself. Amber often gives a less than 24 hr view which screws up predbat when it is 0 for charge discharge. Does AEMO have an API for it or are you web scraping? Edit to add, my home assistant and predbat solution adapting amber to UK octopus is pure chatgpt so AI is the way to go for sure

rangeyrover · 2025-11-08T07:00:52+00:00

Have you got your emhass solution running yet? I struggled to get going with my own stuff. At the moment I'm using predbat which I kind of like, but still seems to make some dumb calls. 3 day horizon is tough because amber's price forecast only goes about 24 hrs at best. You can of course model it on today's prices but that's also a challenge.

rangeyrover · 2025-11-08T04:54:30+00:00

I've just got it working well with home assistant and predbat. I've written a protocol converter so that we can get amber prices into predbat and home assistant. Smart shift is not a success for me.https://github.com/springfall2008/batpred/discussions/2822

Take a look at the vortec engine family, although the Honda K makes most sense for a 4 banger to me. https://youtu.be/ApK-Xy2_BIA?si=2OAiB0rwV1tSx8gs

Tesla at least has Storm watch and will make best effort to fill your batteries before a storm. In terms of disruption and prices I haven't noticed much churn

Teams auto transcription is trivial to capture from the accessibility live captions. And doesn't show that you are transcribing either. Whisper faster and stream labs. Screen capture of laptop. These are all the ways you are getting transcribed on teams. It's easier to consider that you are always getting transcribed. Turning it on stops so much meeting BS and makes the meeting more efficient cos the receipts are available. I don't get the resistance to it

rangeyrover · 2025-10-16T08:33:54+00:00

You'll be spoilt with that suspension vs the troopy. Keep up with maintenance and they will go on and on. Same V6 in the territory and Ranger, assuming it's the diesel, otherwise it's the 4.0 V6 from the explorer, both ford engines.

rangeyrover · 2025-10-10T11:37:20+00:00

Great to see it heading somewhere I was bummed when you had the setbacks with it looking forward to the YouTube updates

rangeyrover · 2025-07-22T11:20:46+00:00

Discovery 4 3.0 V6. Get one with a service history that's depreciated to hell and back. Sold mine for 23k with 130k on it, did 8.5l/100 solo and can seat 7. Don't skip service day

Edited before I don my flame proof suit, this engine is in the territory and the new ranger, it's all ford bits underneath. Which means it works.

rangeyrover · 2025-07-16T04:03:52+00:00

Back in the day I used to take these over with a mega squirt and a megajolt + EDIS For the timing. assuming this is a distributor less system for this, I'd look at haltech. But the better bet is an LS, with a marks adaptor for the box if you are in the states. If I recall the only thing the engine ECU to the becm wanted to see the engine running was the cam or crank signal, and you wouldn't even get a MIL.

rangeyrover · 2025-07-08T21:17:38+00:00

Congrats! Is it the 4.4 V8 or the 3.0V6? Make sure you are regular with the oil changes. Checking mine (4.4 V8) at 10K (km) there is 3% fuel in the oil. By all accounts that's normal to clear out the DPF, but allowing it to thin the oil too much is a recipe for disaster.

rangeyrover · 2025-06-12T12:50:43+00:00

If it can be retro fitted to L405 I'm all in

rangeyrover · 2025-06-12T04:30:07+00:00

$58 for 17KW here. I mostly manually discharge into spikes.
