02
A global team.
SMLIGHT is a distributed company. Our engineering, product and support teams work across multiple regions and time zones, so development and support keep moving around the clock.
03
What we stand for.
Local-first by design
Software and firmware built for local control and Home Assistant — no forced cloud, your data stays in your home. It’s the story our customers actively seek out.
Real engineering
Hardware and software in the same team, on Texas Instruments and Silicon Labs silicon. We don’t sub-contract the hard parts.
Honest with the community
Reviewers get the truth, not a script. Community feedback has shaped our products before, and it will again.
Backed for the long run
Warranty and engineering support stand behind every unit — for the distributors who sell it and the people who use it.
