A generation meter.

Our domestic solar panels have generated more electricity in a year than we have consumed. We installed 5kW of solar panels on our roof in 2020. Half are East-facing, half West-facing. Over a full year, they've generated 4,165kWh. By comparison, the average UK household uses about 3,800kWh of electricity per year. But working out exactly…

Is a smart electricity tariff worth it?

A graph of energy consumption.

(Long and data-filled post ahead!) I've switched to energy provider Bulb (£50 off if you join using that link). They offer a "peak time" electricity charge which looks like this: 23:00 to 07:00 = £0.0815/kWh 07:00 to 16:00 = £0.1235/kWh 16:00 to 19:00 = £0.3263/kWh 19:00 to 23:00 = £0.1235/kWh By contrast, the standard tariff…

What if your Internet Connected Fridge came with free electricity?

A bit of future-gazing which I can't be bothered spinning into a 15,000 word Gartner report. In the UK we have a competitive electricity market. Only one set of wires comes to your house, but you can buy your electricity from a number of providers. Some only offer organic, corn-fed, Wind Farm power - others…

It's The Little Things Which Make An App

by @edent | , , , , | 2 comments | Read ~371 times.

I've been a big fan of Ovo Energy since switching to them last year. They email me a PDF statement, pay me 3% interest on any overpayments, and have their call centre waiting times displayed prominently on their homepage. So, when they announced their new app, I was expecting something a little bit special. And…

How Our Solar Panels Have Performed After 1 Year

by @edent | , , , | 7 comments | Read ~253 times.

Last year, Liz and I took the plunge and had Solar Panels installed on the house we rent out. I've been tracking their progress, and so now it's time for our yearly update. We based our estimations on the Europa Solar Calculator which estimated that they would generate around 2,700 kWh per year. Annoyingly, we…

After my disastrous attempt to upload data under Ubuntu, I found a Windows laptop to upload my energy usage data. The good news is that Sam from Humm is actively working on making the Adobe Air upload application work under Linux. So, how does the process of uploading your data to the service work? The…

Humm Energy Monitor Set Up – Part 4 – Data Upload

by @edent | , , , , | Read ~167 times.

So, I've hit my first snag with the Humm Duet Energy monitor.  As I mentioned in my first post, the device doesn't have any Internet connectivity.  Instead it records everything onto an SD card. In order to visualise the data, I have to manually upload the files to the Green Energy Options MyEnergy site.  Rather…

Humm Duet - Speedometer

by @edent | , | 4 comments | Read ~125 times.

I'll go through all the features of the Humm Duet Energy Monitor as I figure them out, but there's one that I'd like to highlight because it's a perfect example of usability and how a little improvement can go a long way. The left half of the Duet is concerned with electricity. I want to…

My Humm Energy monitor is now fully set up.  It's been churning away gently admonishing me for going over my kWh allowance for the day. As I mentioned in the unboxing - there's an integrated 2GB SD card for the Duet to record the energy usage.  As the trial progresses, I should be able to…

Humm Energy Monitor Set Up – Part 2 - Gas

by @edent | , | Read ~356 times.

After setting up the HummEnergy Duet electricity monitor yesterday, I was pleasantly surprised at how easy the gas monitor was to set up. Pairing the device was easy and the manual was very clear as to which pipes need to be monitored. A velcro strap makes it really easy to attach the wires to the…
