ᐅ Any experiences with Tibber, the Pulse smart home module?

Hello everyone,

We recently came across Tibber and are considering whether it might be suitable for us and economically viable. Does anyone here use it? Specifically, we’re interested in the hourly, dynamic billing and this Pulse device that you need to buy for it. Is it some kind of submeter? They throw around terms like “smart home,” but I haven’t fully understood it yet.

Can the Pulse device be installed by yourself, or does it require a certified electrician? The idea seems to be that it measures electricity consumption in real time.

We have photovoltaic panels, an electric car, and a fairly large battery storage system, so we would presumably be well equipped for this. However, I’m not sure if with our setup we can specifically control if and when power is drawn from the grid. Depending on the price (which can sometimes even be negative), it might make sense to feed everything from the photovoltaic system into the grid and power the household from the grid when the price (like yesterday) was as low as -40ct.

If anyone has any experience with this, good or bad, please feel free to share.

Quite expensive for a summer day – does that include the costs for Tibber as well?

Gross amount including taxes/fees. Without them, the price is exactly 0 cents.

And the much more interesting question is how it will look in winter, when a) electricity generation during the day is very different and b) you don’t manage to fully charge the battery.

a) The standard load curve always looks like that. Peaks in the morning and evening, a dip at midday. Usually, the difference is in the range.
b) I don’t understand that point.

The fees should be included. Tibber doesn’t set the prices itself; they are based on the electricity market.
Maybe it’s cloudy in many places today, I don’t know. On Sunday, the price in the afternoon was, as often quoted, around -46ct.
From the overview, the winters don’t look that different. I assume negative prices do not occur, but there are still fluctuations throughout the day that you can take advantage of in winter as well. If you can’t fully charge the battery via the photovoltaic system, it makes sense, as sysrun says, to charge the battery from the grid at the cheapest time of day so you don’t have to pay the evening peak prices.

Well, what do you do when you pull up to the gas station with an empty tank? Wait for a free fuel canister to fall from the sky, or just fill up as much as you need?

The important thing is how you manage the load. There are consumers that can be easily shifted and actually use a lot of energy. If you have adjusted those before, it’s not only good for your wallet but also for the overall power grid.

If I want to keep the house warm at -20°C (–4°F) and roast a goose in the oven, I’ll do it anyway.

I understand that. My question is, at what level, if the affordable photovoltaic power is not fed into the grid during winter? Would midday prices then be 30 cents and evening/night prices 45 cents?

In that case, you might draw “expensive” electricity from the grid at midday (since your own photovoltaic system isn’t producing), so you don’t have to use even more expensive electricity in the evening. That’s what I meant by “not being able to keep the storage full.”

If you can’t fully charge the battery storage with the photovoltaic system, it makes sense, as sysrun80 says, to charge the storage from the grid at the cheapest time of day, so you don’t have to pay peak rates in the evening.

Especially in winter, battery storage is more or less idle capital. I’m curious to see what I can program for that.

I don’t have a crystal ball. No one knows how things will develop in the next few years as more heat pumps and electric vehicles are introduced and renewable energy increases. Fixed contracts are great, no doubt about it. But they only work well in one direction. Recently, I heard a question about whether electricity providers should be legally required to pass on the reduced costs. Of course not—you signed a fixed price contract. It’s like mortgage rates—you’re betting on the future.

With flexible contracts, at least I have a chance to manage things somewhat. Also, I’m not giving interest-free loans to utility companies (advance payments); instead, I pay my monthly consumption.
