Relaunching @edent_solar. Part 5 - Getting data out of Fronius Solarweb

· 5 comments · 400 words · Viewed ~679 times


A big grey box with lots of wires coming out of it.

Mostly notes to myself. My solar panels have an open API. But it's only available if I'm on the same network as the Fronius inverter. I can connect my system to https://www.solarweb.com/ so I can access it anywhere in the world - if I have the right password. SolarWeb has an (optional) guest mode. You can view the panels' performance if you know the secret URl. It looks something like this: …

My WFH Set Up

· 3 comments · 750 words · Viewed ~1,374 times


A corner desk, laptop, chair, vertical monitor and assorted junk.

Inspired by my friend Meri's WFH Setup Tips, I thought I'd share my home-working setup. We've moved house recently, so I'm still finding my feet - but as I work from home fairly often, and have a bit of RSI, I thought I'd show you what I've got and how I use it. The desk is just a plain IKEA table. Supplemented with a cheap Argos desk which didn't quite fit all my kit - so it becomes a side…

Why would I ever leave my house again? (Do I have Stockholm Syndrome?)

Us outside the opera house.

How are you enjoying lockdown, gang? I think I'm coping well. Perhaps a little too well… I was having virtual-drinks with some friends, when one of them said "How many people just aren't going to want to go back to commuting after this?" I've always been a bit of a homebody. I work from home a few days a week, so the latest shift hasn't been too disruptive. I used to do all my shopping online. …

Hacking your Smart Meter - Part 1 - Zigbee

· 11 comments · 400 words · Viewed ~21,612 times


Zigbee menu items.

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 - this means it can report back to my energy supplier every 30 minutes, and I can…

Some thoughts on selling electricity back to the grid

Email from Bulb saying they've set up an export payment.

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 discrepancy? When I tweeted about this, some people got angry on my behalf. How could I stand being ripped off …

A bathroom sink. The taps are on the opposite site of the sink to the faucet

I walked into an unfamiliar toilet recently. You've probably done the same, looking around to find the stalls, work out whether the driers are near the sinks, if there's soap available. I was completely taken aback when I saw this monstrosity of a sink. It's well known that we Brits love our separate hot and cold taps - but I'd never seen anything like this before! Why are the taps so far away …

This blog strips off for CSS Naked Day

Firefox menu. Go to View, the Page Style, then No Style.

Half-a-dozen years ago, I proposed that web developers spend one day a year browsing without JavaScript. It's a great way to see how the web works when things break. Similarly, April 9th is CSS Naked Day. A chance to throw off the shackles of good design, and see the raw beauty of your HTML. Today is intended for websites to remove their own style sheets - as this blog has done. The idea…

WTF - Welcoming The Future!

App screenshot saying it is now updating the firmware of Liz's bed.

My wife wasn't allowed to go for a post-lunch nap yesterday. Our smarthome wouldn't let her... OK! OK! It wasn't as bad as all that. I built an Internet-connected electric blanket so I can yell at the Alexa to pre-warm the bed. One of the IoT switches needed a firmware update. All over and done with in a few minutes. But I can't help wondering how much time we lose to software updates. Every…

Pause Internet Access on Virgin Media

App screen showing a paused device.

It is a truth universally acknowledged that the WiFi router supplied by your ISP is crap. It will be slow, buggy, and have an atrocious user interface. This is especially true of Virgin Media. The Arris manufactured router is so bad that they've released a supplemental app to help you manage your Internet connection. The app mostly reflects the options in the web UI - but adds one piece of new…

Racist Stickers off our streets

Horrible sticker saying "Europe belongs to the Europeans". Torn down and destroyed.

I've got a "fun" new hobby! Step 1) Find a racist sticker. Step 2) Remove it. Decentralised sticker production is a mixed blessing. Anyone with a printer and an Internet connection can print off dozens of lo-fi propaganda hits. Of course, the crappy stickers were of crappy quality. All the stickers in my community were removed. I reported them to the police, which took the issue seriously …

Netizens or Webizens?

· 3 comments · 250 words · Viewed ~375 times


Screenshot from a Guardian article about Chinese Webizens.

Way back in the 1990s, the word "Netizen" was coined. I always took it to mean "someone who lives on the Internet". In modern times, the neologism has been superseded with "webizen". I find this an interesting development. It is well known that people often confused the Net with the Web. Hence the need for these "explanatory" t-shirts: Of course, the original meaning of Netizen was…

The Laptop of Theseus

Laptop covered in stickers.

My laptop battery has died. It was working fine yesterday, but today I shifted slightly on the sofa, dislodging the power cable and the laptop blinked out. It still works when tethered to the wall - but the battery is shot. TIME TO BUY A NEW LAPTOP! Because shipping in non-essentials from China is so easy right now... Nah, I'll just replace the battery. A fifteen quid job rather an a grand…
