Indoor Grow AutomationCH-03 / GROWMAX · ORIGINAL PRODUCT
Indoor grow automationwithout a subscription.
GrowMax boards and kits monitor moisture per plant and water on schedule. MicroPython firmware running on whichever Pi-Pico-pinout microcontroller you drop into the headers — no cloud lock-in, no monthly fee, the source is open. Built for indoor growers who'd rather understand their setup than rent it.

LightNVRCH-04⅔ / NVR · SISTER PROPERTY
Network Video Recorderthat end users love.
LightNVR is an open-source network video recorder that runs on low-resource hardware — a Pi, a thin client, an old NUC. RTSP and ONVIF cameras, on-device motion detection, footage stored where you store everything else. There's also a managed cloud at lightnvr.com if you'd rather not host it yourself.

Solar that tells youwhen it stops earning.
Solar Monitoring Alerts watches your inverter and sends a heads-up the moment production drops, an inverter goes offline, or output diverges from forecast. Daily summaries, real-time alerts, and historical kWh — all without putting new hardware on your roof.

Books that almostbalance themselves.
OwlBooks is the OpenSensor sister property for double-entry bookkeeping — built for engineers, freelancers, and small businesses who want a real ledger they own and can audit, not a SaaS subscription that re-prices itself every January.
