How exciting! I didn’t realise you could tag people in iMessages.

Don’t let them grind you down paper leaflet ✊

Does anyone know why AirTags are magnetic?

Bonus: They’ve started paying for themselves.

Tado Wireless Thermostat stand

Tado have now released a stand for their wireless thermostats (and wired air-con controller, but I don’t have one of those) and it looks good on a nightstand.

We chose Tado for our smart heating as it offers TRVs to control individual radiators. These work, but the temperature sensing (unsurprisingly for something immediately next to a heat-source) wasn’t the best. Adding wireless thermostats to rooms where that mattered made a big difference, but left me with the same challenge: how to place them for best accuracy if there’s not a bit of wall to stick them on in the ‘right’ location.

TIL cows aren’t interested in head-scratches but would quite like to lick your iPhone.

The child and I made Salmon En Croute and the hours of plasticine play paid off.

Colour temperatures of default Hue presets (for White Ambiance bulbs)

I couldn’t find this data for my own use so I collected it by setting my Hue lights into each of the default scenes for ‘White Ambiance’ bulbs and reading the colour temperature for each.

This list is from warmest to coolest:

  • Nightlight: 2237k (447 mireds) at 1% intensity
  • Relax: 2237k (447 mireds) at 57% intensity
  • Dimmed: 2725k (367 mireds) at 30% intensity
  • Bright: 2732k (367 mireds) at 100% intensity
  • Read: 2890k (346 mireds) at 100% intensity
  • Concentrate: 4292k (233 mireds) at 100% intensity
  • Energize: 6410k (156 mireds) at 100% intensity

This should help align colour temperatures between smart lights (and normal ‘dumb’ bulbs) where needed. Unfortunately Hue’s own app doesn’t display colour in numerical format.

Hue and Home Assistant (by default) set colour temperature in Mired. SmartThings (and normal ‘dumb’ bulbs) use Kelvin.

He even brought a date.

“You planning on eating all of that?”

Hooray! My @chimneyfirec coffee order arrived with a lovely handwritten note and a sticker!

Had lots of recommendations for this firm that are local to me. Long overdue order.

My stickers arrived in the UK! Thanks @jean 🙏

Simiar to this chap my warranty documentation for AirTags and accessories shows dates as far back as 2019, but the product packaging is all March and April 2021. I guess 2019 was when some of the packaging design was done?


These are brilliant. Completely change our Hue setup to operate from our existing switches.

Today’s watch is my Christmas present to me - the Hodinkee colab with Merci Paris. I love the saturated blue hands and the typeface.
