Six Sonoff Zigbee valves behind a master valve with a flow meter, two soil probes, a rain forecast and one 03:00 Home Assistant automation water the garden. What each part does, why the gates fail open, and the one MQTT command that took longest to get right, with a gist to copy.
The filter and the 200 m roof-coil heater now run on the PV forecast instead of a fixed schedule. Four weeks of numbers from a 13 m³ pool: 104 solar-pump hours for 46 kWh, a 2.8 °C lift in five days, and what a 650 € pool costs to keep for ten summers.
Mitsubishi Ecodan in Home Assistant: MELCloud, then an ESP32 on CN105, then ESPHome. What a winter of counters showed and the automations they drive.
Four years of invoices and inverter data from a 6.4 kWp zero-export rooftop PV system with a BYD battery: what each part cost, what it saved, and which one was a bad buy.
A Sofia hail storm dented cars and flooded ground floors. Now a script decodes RainViewer radar into hail and lightning ETAs, pushed from Home Assistant.
Visited the Seven Rila Lakes today – well, five of them. Stunning place. Go if you get the chance
Turning an X (Twitter) archive export into native WordPress posts – 1150 tweets filtered and merged into 518, media sideloaded, my words back on my own domain.
No VPN client, no port forwarding – the Guacamole add-on in Home Assistant gives me VNC to my Mac from any browser. It’s just another item in the sidebar now
I kept missing deadlines buried in Facebook groups, so fbtool scrapes them with a logged-in browser and an LLM turns them into a two-minute daily digest.
Безплатен уеб тренажор за подготовка за НВО и матурата по БЕЛ: 256 теми, 20-минутен таймер, оценка по критериите на МОН и подробна обратна връзка.
Tesla Model 3 dead overnight with a false “High Voltage Fuse A Blown” alert – reconstructed to the second with Home Assistant, TeslaMate and BLE.
Three years of Fronius GEN24 data distilled into a clear-sky ideal-produce curve as a Home Assistant sensor – the fit, the validation, the surprises.
Wanted my PV history out of Fronius Solar.web, but there’s no bulk export and the official API is paywalled. So a 277-line Python script now does the login and dumps 4 years of production, battery, EV, and Ohmpilot data to CSV – 5 min to yearly. https://github.com/mharizanov/solarweb2csv
How a broken auto-updater left my blog open to a WordPress core RCE (wp2shell, CVE-2026-63030) and the boring IP rule that saved it anyway.
41.7 kWh produced and 100% self-consumed today from our 6.4 kWp array today Battery was capped <90% SoC (HA automation, summer heat – keeps the LFP cells happy long-term), so most of that went straight to loads, hot water and the car rather than storage. Overall just about 1MWh production in June, with one more…
Anthropic’s Fable 5 available in Claude That didn’t last long..  but what were they thinking to begin with? Marketing it for months as “too dangerous to release”, then when the govt believed them, it’s an “oops”..? I believe the ban won’t hold up though.
€14.5k into DIY solar in 2022, or the same into VUAA? ETF would be up ~€12.5k on paper, ~€7k after inflation. But the panels generated 27.7 MWh so far – that’s ~€3.5k of grid power I never bought. real gap: ~€4k and shrinking every year electricity gets pricier. no regrets
Our Tesla M3 efficiency vs. outside temperature stats for the last 10K km driven, collected using TeslaMate. No surprises here, driving at 20 °C outside is most efficient
NotebookLM MindMap of my quotes collection
Reflective stickers on my DJI Mini 5 Pro to help keep birds away. Registration and phone number printed in bright yellow – easy to spot, and the bright color maybe helps with birds too.
Built a tool to help my daughter prep for her 10th-grade national exams and 12th-grade matriculation exams -and, without her knowing, set a little trap to catch AI use. Well, it sprang sooner than expected 😂
Got an electric @STIHL trimmer – tired of the fiddly, needy gas one. Loving it. Might go electric for the mower and chainsaw too. One only needs to remember to change the battery upfront..🪫
Rate my burgers 😅
How an AI agent decrypted the local Viber database on my Mac in seven hours – a research experiment showing the technical barrier to hacking has collapsed.
Free image diff tool that compares two screenshots or diagrams in the browser – auto-alignment, five comparison modes, no uploads to anyone’s server.
At BASSCOM AI conference in Sofia, Anthropic’s Patrick Dreisch delivers interesting insights now He says AI capabilities double every 7 months now This stroke me deep – “people are the bottleneck” by EnduroSat’s Krasi Stoev. Sad but true
Vibe-coded a 2D orthophoto/3D point cloud viewer so I can share my drone-captured collections with friends. It supports WebODM exported assets.
My GitHub contribution stats before/after GitHub Copilot Pro subscription. What do you make out of it?
Have not paid for EV electricity since late Feb, going purely on solar. More than 800km driven so far, feels illegal.
Emergency revival procedure started; vibe-coding session interrupted 🙁
So Cuba is next?
Today's 60 km EV commute's spent energy is fully recovered by free solar charging once back home. And it's still only February. Impressive.
