First, let me say that I like what you folks are doing here, and with each step forward, I nod to myself and congratulate you on staying true to your original vision. The platform seems solid, and the direction clear.
I have two hardware monitors from two different companies. Both of them connect to Apple HomeKit and tie into my smart home. I have over 106 devices connected to my home intranet, and some of those are hubs that have dozens of devices behind them, so I'm not kidding when I call it a smart home.
One of the monitoring devices measures humidity, temperature, and motion, and can be set to provide alerts or triggers based on these things. For example, I can make lights on my Hue system turn blue when the temperature drops below a setting I define, or red when above it.
The other device measures humidity, temperature, and very low levels of carbon monoxide that wouldn't trigger a standard carbon monoxide detector (which is critical for young children and babies). Again, notifications and triggers of my choice can be easily defined and set.
The Points measure noise levels, which is valuable, and I see you working on better defining that alert so that it isn't just "too loud" but "smoke alarm" or "glass breaking" or perhaps, in the future, "loud noise when it is normally quiet."
I don't know where we are with the air quality sensing. I've asked several times now, and have been told people are working on it. But, it seems odd to me that it doesn't exist at all, in any form. Also, I don't believe it was ever really defined. Is it measuring particle counts? VOCs? Something else? Air quality can mean many different things.
I'm also wondering if you've considered an optional hub to tie the Points into HomeKit. If you did this, they could be tied into the overall smart home ecosystem and work with other devices in that space. Turning the lights different colors was the example I used earlier, but there are many other possibilities once this is opened up. A hub could also connect them to IFTTT, which would open things up even further. It wouldn't be an easy task and would require hardware development along with certification from Apple, but I'm beginning to realize that it is necessary for the Points to have a future beyond themselves.
I guess this was a combination of a few questions along with some food for thought. I hope that you will consider it, and also take it in the spirit of helping that it was given.
