Technical insights
We build from evidence.
Engineering notes on the problems behind our products: local control, data ownership, extreme low-power electronics and systems that keep working without mandatory dependencies.
Every article separates published specifications, bench evidence, engineering judgement and facts still to be confirmed. Read our editorial and technical method.
Hardware power latch or deep sleep?
Two different ways to leave an IoT node waiting. What remains powered, how wake-up works and when a few nanoamps materially change the energy budget.
Read the insight → LUMA-6CH / ControlWhat does local-first actually mean?
A connected controller should not stop working when the internet or its vendor is unavailable. We define which functions must stay local and why.
