Open the box. Build it tonight.

Every kit is flashed, wired and tested on our bench before it ships. Working firmware already on the board, a step-by-step guide in the box, and Home Assistant auto-discovery where it counts. No cloud, no accounts, no telemetry.

Kit questions

What does “pre-flashed” actually mean?

The firmware is already compiled and flashed onto the board before shipping. Power it up, follow the guide, and the project works — no toolchain setup on day one. It is still a standard ESP32: flash your own firmware over it whenever you are ready.

Do I need a cloud account or subscription?

No. The Home Assistant kits auto-discover over your own Wi-Fi and keep working if the internet goes down. No accounts, no telemetry, no monthly fees — you own the whole stack.

Can I buy the parts individually?

Yes — every board, sensor and module is also sold separately in the shop. Kits exist because the bundle is cheaper than the parts plus shipping, and the firmware is already tested on exactly those parts.

What about shipping and returns?

Tracked worldwide shipping, and 30-day returns if the kit is not for you. Details on the shipping and returns pages.
