We recently upgraded our home solar storage to 4.8kWh. The battery has sensors to detect how much solar power we're generating, and how much electricity we're buying from (or selling to) the grid. That means... GRAPHS AND STATISTICS! Our battery was commissioned just after midday. This graph shows: 1630 - it was fully charged. 2000 […]

The first indication I had that anything was wrong at home was my solar panels's cloud service casually emailing me to say they hadn't generated any electricity that day. We were on holiday - literally on the other side of the planet - and there were reports of snow at home, so I didn't think […]

Electricity demand varies throughout the day. When demand is higher, electricity prices go up. Most UK consumers are insulated from this variability - we pay a fixed price per kWh no matter what the actual wholesale cost. But it doesn't need to be this way. Exposing users to the immense variability in pricing is probably […]

Every few years, a dodgy stat does the rounds claiming you can save £££ if you switch off all your gadgets at the wall. The standby mode of your TV is bleeding you dry!!! A quick way to #saveenergy at home is to turn off tablets, laptops and consoles as soon as you stop using […]

I never get power cuts. But, we've had two in the last week. They've both been fixed quickly, but it takes an age for my cable modem to reboot - and then an age for my smarthome to reconnect to the WiFi. So it was time to invest in an Uninterruptible Power Supply (UPS). My […]

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 […]

A few years ago, I took part in a local trial to install a solar battery in our home. The battery was excellent - and made a reasonable difference for our energy use. Sadly, last year, it died. It was prototype hardware, and these things happen. Moixa offered to replace it with an updated model […]

I can't find these instructions anywhere online - so I hope these notes help! The AS302P SMETS2 has two buttons. I've labelled the top button A and the bottom button B. Press the A button once to bring up the menu. The display should light up. It should show "General". Press the B button. This […]

I have a new Smart Meter to measure my electricity and gas usage. It's the Honeywell AS302P. It's a SMETS2 meter, which means it has a number of interesting features. ALCS (Auxiliary Load Control Switch) - this means that a car charger can be remotely started and stopped based on network demand. DCC connection - […]

I have solar panels! The UK mandates that my electricity supplier buys the surplus energy off me. They set a minimum price, known as the SEG (Smart Export Guarantee). My supplier - Bulb - pay me 5.38p for every kWh I export. I pay them about 13p for every kWh I import. You notice the […]
