RainCo-MCS

RainCo-3 is a conductive controller for misting systems for terrariums.
What makes it special is the ability to use a single pump and a valve system to control multiple spray circuits with different parameters (spray duration and spray timing).
These controllers can supply up to six spray circuits with a single pump and water tank. The whole system can be conveniently operated via the web interface, but can also be controlled via the ‘Home Assistant’ smart home control system.

The latest information can be found in the Facebook group: RainCo-MCS

Caution
This project is a DIY project!

I do not offer complete "ready-to-run" systems.

You can only purchase a kit for the control board from me. All SMD components are already installed. Only the THT components (THT = Through Hole Technology) still need to be soldered.

I will try to describe all other necessary steps and components as accurately as possible.

Note
I am planning a small series of 10-15 pieces for Februar - March 2026.

This includes the RainCo-3 circuit board. All SMD components are soldered on.
The THT components are included in the delivery, but must be soldered by the customer. This takes a maximum of approx. 20-30 minutes. The ESP32S3 controller is not included!

The cost for a kit is €58 plus shipping (€7 within Germany, €15 within the European Union; insured parcel in each case).

If you are interested in an ESP32S2 controller with pre-installed firmware, this costs an additional €17.

Furthermore, a housing (bottom part, top part and front panel) can also be purchased in small quantities for €18.

If you are interested, please feel free to contact me.
