Zigbee / Matter Motion Switch | Project Linus (Blue Series)

Great question – I’ve updated monthly via Indiegogo, but I should probably get a mailing list together or something as some people haven’t ordered through Indiegogo.

To catch you up to the parade if you’ve missed it, the last update I mentioned that we would have to push back the production schedule as we really wanted to push to add in lux monitoring which we ended up being able to do. This caused a delay.

This month, we also ran into a snafu in that the mmWave sensor we were going to use tested poorly (HiLink) and their specs did not match what we were promised. I think they were hoping we wouldn’t test the module prior to purchasing it or something as we tested their module alongside two other ones that were similar size and theirs performed the worst. Very disappointing.

We’ve settled on a new mmWave sensor that has a better field of view (150° as opposed to 120°) and tested the best. Much of the month was spent negotiating the price, redesigning the PCB and testing.

All this has caused a three month delay with most of the delay coming from Chinese New Year. We’re targeting March 25, 2024 for Mass Production.

That said, a three month delay in exchange for a lux sensor + a better mmWave sensor than what we originally scoped seems like a fair tradeoff. Disappointing, but it could be worse.

I will update the timeline shortly.
