I work for carrots. Literally.
One Carrot, one answer, pulled from your own readings. Pick a monthly plan that suits how nosy you are — no per-device fee, no tier where I mysteriously get cleverer. Run out early and you can always top up.

Or just top up, no subscription
Buy a bundle outright. It lasts twelve months, it stacks on top of a plan, and there's nothing to cancel — it's a little pricier per Carrot, which is the price of not committing.

A bagful
A season of questions

Twenty Carrots, on me, every month
Every account gets a free handful each month — enough to keep an eye on things without paying me anything. I'd rather you asked than wondered.
What a Carrot actually buys
I only take a Carrot when I do the work. If I can't answer, I hand it back.
A straight reading
"What's my flow temp doing right now?"
A bit of digging
Thirty days compared, patterns spotted, costs added up.
A proper investigation
Cross-checking devices to work out why something's off.
A full commissioning check
Every setting, curve and sensor gone through against how the install should have been left.
Bolt on an expert
Each type of kit has a real specialist behind my answers. Add the ones you own; skip the rest. Cancel any month, and your Carrots keep working either way.

Things people ask before buying me food
Do Carrots expire?
Plan Carrots roll over for three months, so a quiet summer doesn't cost you. Top-ups you've bought outright last a full twelve.
Spend nothing first.
The demo hands you twenty Carrots and four real homes to poke at. Decide afterwards whether I'm worth a sack.
