I could stick a probe to the surface of the tiles. It would be hidden from view.

Mine is in a conduit, but I doubt it would come out. I would like to just drip feed it power at fixed times in the day. Maintaining a low temperature rather than the wild swings we get now.

The probe changes in value, but I think there is more residual heat beside it as it’s in a groove in concrete backing board. I feel the tiles go cold, but the probe is swimming in heat 😂

I can thinking of nothing better than recreating the heat of Dubai’s sands on the floor of my bathroom 😂😂😂

I’m glad I’m not the only one! PWM is probably the solution. The equipment to throttle current might be too big 😂

The floor just always seems cold unless the relay is on. The thermostat probe is *useless*. Reports 21, floor feels cold. Reports 18, floor feels cold.
It’s only when it actually switch on that the floor will feel warm. I think I messed up when installing the probe.

Is there an electric underfloor controller that can modulate? I have a standard on/off and it’s shit.

iOS 26.1 is out.

That vacuum pump looks nifty. Might invest in one of those for V2 of my board.

I’m getting better. Just need more practice.

Fingers crossed I’ll be able to program the module!

I have a hot plate and some solder paste, but the process hasn’t been very successful for me. I think I’ve been using too much paste 🙄

I only have a few components on each board and some are through hole, so hopefully it will be fine.

Going for a proper module instead of a dev board this time.

Some JSON from the Octopus Energy Graph API showing a node with the name "Free Electricity '24" and a slug of "free_electricity"

@octopus.energy Hi! I was looking your API last week and found this little titbit. The free electricity sessions have "'24" in the name. Would I be right in saying this could be 25?

PCBs arrived from @aisler.net. Only one of them has a short! That’s not a design flaw, but a tolerance thing. This is the most complex PCB I’ve designed. Sweating at the thoughts of placing the tiny components!! 😂

In this post I try and get my Matter Dual Temperature sensor code working on the MinewSemi ME54BS01 module (spoiler: I did!)

Ah, okay. That makes more sense. Like three phase here in the UK, except the majority of homes only get connected to one phase.

Got some new tips for my Pinecil. Hopefully this will make soldering the SMD components a little easier!

Ahhhh, that’s interesting. So 240 is supplied to the home, but most outlets only get 120? Is there a transformer?

I guess it’s the switchover that would be extremely difficult. How would you manage that?

Nigel Farage Says Minimum Wage Should Be Cut for Young People The Reform leader said cutting the minimum wage for young people would boost business, as he attacked plans to raise taxes on the wealthy

YOUNG PEOPLE. LISTEN UP.

Today Nigel Farage said the government should cut the minimum wage for young people

...to “raise aspiration” and “boost business"

It's £10ph FFS!

Lower your pay so you’ll dream bigger

DO YOU SEE IT NOW?

Spread far & wide.

Do you see any errors in the Home Assistant logs?

Hi. It should work, but yes, it’s possible it no longer works.

My parts arrived!

Fumes and neon?

Following this project with interest!

Three weeks?? I can barely handle one.

To quote Sherlock Holmes, “my mind rebels at stagnation”.

That said, holidays are good for switching off. Ive been mentally exhausted for a few weeks now, so it’s been good to get a break.

I knew crows were clever….but opening a packet of sugar is pretty smart!

That’s cool!
