The problem we keep hearing about

Almost every humidity complaint in this hobby comes down to the same three things:

  • Timers don't know the weather. A misting system on a schedule keeps misting when the enclosure is already soaked, and stops when it's bone dry. You end up adjusting it constantly, or fighting mould.
  • Cheap hygrometers measure but don't control. They tell you the humidity after the fact. Most keepers end up buying a monitor and a controller — two devices that don't talk to each other.
  • The one combined unit has a poor reputation. The mainstream temp+humidity controller is known for being unreliable, and the reliable premium brands cost more than most people want to spend on a single enclosure.

What we would build

A low-voltage controller that reads temperature and humidity, and drives a misting pump to hold a target rather than run on a clock. Concretely:

  • Closed-loop humidity control — it reads the real humidity and stops when it hits your target, instead of guessing from a timer
  • Temperature sensing in two places — basking surface and cool end, so a proper heat gradient is measured, not assumed
  • Failsafes that assume things go wrong — pump run-time limits so it can't flood, and a hard stop if a sensor fails rather than blindly continuing
  • Local control, no cloud account — works over your own Wi-Fi, with a small screen and buttons so it works even with no network
  • Home Assistant friendly — for the minority of keepers who run one

What it would not do: switch mains power. It's designed to sit alongside your existing heat thermostat rather than replace it. That keeps it safe, cheap to certify, and means you don't have to throw away gear you already own.

Pricing is one of the things we're testing below — so we're deliberately not anchoring you with a number first. Please answer the price questions with whatever feels true to you.

Tell us if this is worth building

Six questions, about two minutes. Only your email is required — skip anything you don't want to answer, and that still helps us.

We'll email you once when there's something real to say — a launch date, or a decision not to build it. No newsletter, no drip sequence, no sharing your address. Unsubscribe link in every email.

What would you expect to pay?

Four quick questions. Give a dollar figure for each — first instincts are fine, and there are no wrong answers. This is how we work out whether the thing is buildable at a price anyone would pay.

Be honest — we'd much rather have a truthful "just keep me posted" than a polite yes. Saying yes to something you wouldn't do is the fastest way to make us build something nobody buys.

We are not taking any money on this page. There is no product yet and no shipping date. This question only tells us how strong the interest is.

By submitting you agree we may email you about this product. We'll never sell or share your address. See our Privacy Policy.

What we'll do with this

If enough people tell us this is worth building, we'll build it and email you. If the numbers don't add up, we'll say so publicly on this page rather than quietly dropping it — a negative answer is still a useful answer, and we'd rather you knew.

We're not collecting this so we can hammer you with marketing. There is no product yet, we have nothing to sell you, and the honest state of play is: we don't know whether this gets made.
