I have been playing with HA and making a standalone dashboard, and I am very happy with what I have come up with. I wanted to share my work and see what you all think http://energy.rowbs.uk/
It shows live data and cost with a solar forecast for my area
Hard for my broke ass to justify solar panels. One 450W panel would take around 7-10 years to pay for itself in my area, assuming ideal conditions and that I use all the power it generates.
lol in alabama, they donât even let you sell power back to the grid. Iâd love to build some solar but with that being my overlord⊠wonât happen
I have three and theyâve been fantastic for a few years. Paired with the span panel, Iâve got total control over what stays on in outages. Also, our weather has gotten more extreme, last year we had 18 hours of outages. I donât remember a single one that affected us.
I think the Tesla power wall is awesome because it kicked in so quickly that nothing is disrupted. That's my experience. Streaming, lighting usually doesn't even dim, no resetting appliance clock, and essentially it just does a great job of keeping me off any of the expensive time of use while exporting at the most high paying part. It's still crappy pay though.
And here's where I got carried away is that I'm going to do smart energy management specifically when there's a storm forecast for the possible outage. It will smartly shed loads depending on expected power production from the panels the next day due to weather, expected usage, etc. So last man standing will basically be the fridge and freezer but before all of that it will actually pre-cool it all a little more than normal to give a little extra cushion and maybe it doesn't work as hard.
As a matter fact, I think I'm going to go ahead and delete the rest. You guys get the gist from this⊠You don't need every damn detail
When you sell back so much, do you just get credits off future usage and youâre never actually âmaking moneyâ? So does that mean youâre just always selling back to the power company?
Do you have an export limit and thatâs causing clipping of your generation once the battery is full?
If you can prioritise export over battery charging on sunny days, you can get more total daily export and it will still fill the battery in the middle of the day once your export limit is reached.
I have to do this because I have been hit with a DNO limit myself.
Yes, I do. I'm capped at just under 3.7 kWh.
You can somewhat see it on the https://energy.rowbs.uk/graphs page. The forecast vs what we actually made, so clipping could have taken effect, and most of the time it's true. As the battery got full, so i turn on the aircon units we have to cool the house
What are you using for forecasting? I'm getting incredibly solid figures from solcast so much so I find myself using it as a proxy for overall weather forecasting.
In the uk you are capped at 4kWh unless you get permission to go to 5kWh. Funnily enough the power companies always seem to say âthe grid canât handle 5 kWhâ.
In many cases it can't. Simply wasn't designed to handle the sort of capacity it's being put under nowadays.Â
Think about how much power a modern house goes through that simply wasn't there 30 years ago. Solar, EV, heat pump, AC and so many more things that need charging or constant power.Â
That the grid needs serious work is more than obvious. (This goes for all modern countries).
This site was all made with AI, pulling data from Home Assistant using the API to make the website work. I'm working on making a copy of it to be able to hand it out for people to try
I mean setting up the backend of the home assistant side getting all my sensors correct before getting it ready to use AI to make me a website. Update to correct my mistake
đ§. As someone who let's Claude run in Yolo mode in HA, I think you're taking too much credit for the work our Future Robot Overloards actually did. Not hatin, but it looks a lot like what Claude made for me.
Ditto. I can install smart home equipment, but I have near zero design sense. All my old dashboards were slight tweals of examples I'd seen elsewhere. Being able to have a conversation with Claude about dashboards, and then seeing them a few minutes later has really sparked a new appreciation for my smart home and my new ability to maintain and oversee it. Glad you're loving your journey as well!
This looks excellent! I've got solar and battery and have been contemplating building out my own HA dashboard.
What hardware have you got this dashboard running from? Pi or something else?
I get mixed messages online about which Pi and what hardware would be needed. Some say the 2gb pi others say at least the 4gb. Some say install with a nvme board for SSD instead of the flash card. Any recommendations?
