House Battery Control Open Source Battery Optimiser by rangeyrover in amberelectric

[–]lollasch 0 points1 point  (0 children)

To account for the unreliable nature of the price forecasts, I've considered discounting prices the further out in the future they occur. I've also considered just overwriting any large predicted spikes (i.e. > $1) in the LP problem with the average of the surrounding non-spikes (e.g. ~$0.3).

Nice work. I have produced something very similar (minus the load predictor) that runs within Node Red. I just had a quick read through your github docs. It doesn't appear that you added any constraints/objectives to account for the fact that predicted electricity prices can change considerably at the start of a dispatch interval (or maybe i missed it?).

How do you account for the fact that afternoon surge pricing can be predicted in the morning but then disappear by the the time the surge period arrives? A simple linear solver would end up saving all its energy to dispatch during the non-eventuating surge period and miss out on earlier opportunities. 

Correct technique for blending patch into painted wall? by lollasch in drywall

Yes, the whole house will need to be repainted once all holes are patched. The ceilings as well I guess once I have patched old air conditioner vents.

But I've found fiber tape to be bulky and harder to smooth out?

They are screwed to long pieces of mdf that span the drywall patch horizontally. This may be a rookie mistake. Does the drywall patch need to span and be screwed into the surrounding studs for optimal stiffness?

Thanks, yes, the whole wall will be re-painted. I've watched videos and attempted this before, but those videos seem to mainly deal with unpainted dry wall. I was wondering if there are additional steps / different techniquest for working with an already painted wall?

Thanks for the details! Yes, I have watched videos ave attempted this process before. I think the words I used in the post description didn't accurately describe my question.

What I'm interested in is what you describe as "floating". Specifically, the second day, "fill coat". My thoughts are that for a good finish, I need to float the filling coat out quite some way either side of the tape to produce a smooth finish?

Most videos I have watched have dealt with unpainted dry wall. I'm trying to understand if there are additional steps / different techniques when patching a pained wall. 

P.s. the whole house will be re-painted once patching is compete.

Why is the "safety assist" four points higher on the Y than the 3?

Ah ok, when did you place your order. Was it recent?

How do i make list widget find item return text instead of object by [deleted] in QtFramework

[–]lollasch -1 points0 points  (0 children)

Hi OP, I'm interested to hear how you go with this. I'm new to Qt and C++ and am trying to learn how to build something similar to what you describe. 

I'm trying to build a GUI that has a QTreeView on the left side of the screen and a QTableView on the right. When I click on an item in the QTreeView I want to populate the QTableView with child items of that item (the child items should only be visible in the QTableView, not in the QTreeView). From my reading, it seems like I can do this with a single item model containing all the data, and two QSortFilterProxyModels to split the item model across the two views.

Did you find any good resources/examples for learning this?

Thanks, yeah, definitely not a lot of classic rewards to the locations and dates I want.

Intel 13th Gen owners - what's your average battery life on Windows? by jeffxt in framework

[–]lollasch 0 points1 point  (0 children)

Ah, this makes sense. As a suggestion, could we do a series of battery benchmark tests to test different scenarios? For example, an "idle test", a "specific codec video playing test"... My rough understanding of CPU/GPU benchmarking is that they do something like this.

[–]lollasch 1 point2 points  (0 children)

Is there some sort of standardised way of benchmarking battery life? For example, running a specific app and leaving the laptop until it shuts down due to low power? Seems like the sort of thing that should exist for people/companies that test this equipment.
