35 and 45 WiFi devices at home
How many WiFi devices at home is 'too many'? We have between 35 and 45 depending on who's home and which devices are active. A mesh network of four routers provides the needed coverage.

Old Nissan Leaf batteries to a Fronius GEN24 inverter
Thought I was done with solar system spending, but then someone develops a way to connect old Nissan Leaf batteries to a Fronius GEN24 inverter. Now remains to make a compelling case for this new budget dent to my better half. https://github.com/dalathegreat/BYD-Battery-Emulator-For-Gen24 Repeating in my head: "want != need"

UltraFires, hoping they don’t live up to their name
I'm uncertain about the thought process behind this battery manufacturer's brand name and logo. Both seem to have been deliberately crafted to raise eyebrows. Hack charging those odd-sized “UltraFire”s, hoping they don’t live up to their name and catch an ultra fire

Power Flow Card Plus visualization
Just integrated the "Power Flow Card Plus" visualization into my #HomeAssistant system. Loving the seamless synergy with every aspect of my #Fronius ecosystem, from #SolarPV to battery, #EV, surplus hot water tank diverter, and grid usage.
The Sun’s manufacturer is listed as unknown
The Sun's manufacturer is listed as "unknown" on my home assistant dashboard. Must be some sort of a covert operation of cosmic proportions?
Our DYI air-to-water heat pump
Our DYI air-to-water heat pump has officially reached the end of its 13-year service life, conveniently at the conclusion of this heating season. We're grateful for the reliable warmth it provided and look forward to replacing it with a new system during the summer months.
llama.cpp with the 30B param LLM on my laptop
Testing llama.cpp with the 30B param LLM on my laptop. It can write code, but be prepared for a wait – the following snippet took over 20 minutes to generate.
HTTP error code 418 I’m a teapot
Did you know about the HTTP error code 418 – "I'm a teapot." It originates from the 1998 April Fools' Day RFC 2324, and is part of the Hyper Text Coffee Pot Control Protocol. #HTCPCP #Error418

Question the clichéd 'Happy Friday' hype; find meaning and joy beyond the confines of one day. #BeyondFridays
Selective type RCDs exist
TIL that selective type RCDs exist. I learned this lesson after an RCD in my DIY emergency power switchover box started tripping more often than expected. The schematic indicated a type S RCD was needed, but I didn't understand what that meant until today. https://www.electrical-installation.org/enwiki/Coordination_of_residual_current_protective_devices

Green metallic beetle’s larvae
Our composer is infested with that otherwise beautifully looking green metallic beetle’s larvae. I need to use the compost now. Are the larvae pest (kill) or harmless (move elsewhere)? Never mind, our daughter came to see what the fuss is about, and “kill” is no longer an option. She is supervising the moving now, but…

Wireless outdoor temperature sensor
Had to move a wireless outdoor temperature sensor I designed ages ago, noticed a memo inside I left for the future self with last battery change date. Still sending readings every minute since May 2018, thats 4 years and 9 months on couple AAs and still going strong. #IoT #rfm69

LiFePo4 (LFP) chemistry
Interesting paper on "Degradation of Commercial Lithium-Ion Cells as a Function of Chemistry and Cycling Conditions" here: https://iopscience.iop.org/article/10.1149/1945-7111/abae37/pdf; Three degradation factors are explored: 1) Temperature, 2) DoD and 3) Discharge rate. (1/2) I specifically care about LiFePo4 (LFP) chemistry, because our solar system's BYD battery is such. Strange to see that a 100% DoD doesn't…
BYD HVS 7.7kWh BMU update
Our solar system’s battery app (BYD HVS 7.7kWh) says its BMU needs an update. No release notes or details on what’s being fixed. Feeling brave and proceeding with the update anyway, WCGW
Twitter verified blue badge
Briefly entertained the idea of getting a Twitter verified blue badge now that it is available in Bulgaria, so that I could parade my superiority over non-verified users.
Caffeination hardware
Upgraded our caffeination hardware to better enhance our cognitive functioning on early mornings. Latte art skills remain at near non-existent level with no tendency of improvement.
VW ID3 facelift hardware climate control buttons
The VW ID3 facelift was just announced, but it still doesn’t add backlight illumination to the hardware climate control buttons.. what are they thinking?? I refuse to consider buying a 45K+ EUR car that has me guessing what am I pressing in the dark.
