Custom ESP32 Controllers
Purpose-built wireless controllers using ESP32 hardware, displays, sensors, relays, and custom enclosures.
The challenge
Some control problems have no clean commercial answer—the right combination of inputs, outputs, display, and connectivity simply is not sold as a single product, or the products that exist depend on a cloud service that could disappear.
The solution
We designed a family of ESP32-based controllers pairing displays, sensors, and relay outputs in custom enclosures. Firmware built on ESP-IDF and ESPHome exposes each device cleanly to a local automation platform, so the controllers integrate as first-class local devices rather than cloud-tethered gadgets.
Outcome
The controllers provide exactly the inputs and outputs a given task needs, in an enclosure sized for where they mount, and integrate locally without external dependencies.
Lessons learned
Designing around a small, repeatable hardware pattern made it far faster to spin up a new controller variant. Standardizing the enclosure and connector layout early paid off across every follow-on build.
