App idea for someone: make a simple alarm.
I have a few Nest devices, and they all do motion detection. If I'm away for a few days, I'd love an alert if my Nests detect someone in the house. It could alert me to check a security camera, and then to call the police.
It could do fancy stuff, like only alert me if I'm not at home by checking my phone's location. Or perhaps you could set off the fire alarm to try and ward off intruders.
I imagine alarm systems are on Nest's roadmap. I'd be worried if I was ADT.
- vicaya 13y agoNest is reinventing home automation badly, IMO. You can already do all that and more with plethora of Z-Wave devices with Vera* without any external services.
- dangrossman 13y agoOne z-wave motion sensor and the cheapest Vera hub would cost $200-250. Getting more out of the Nest he already owns costs $0.
- vicaya 13y agoA motion/temperature sensor from Monoprice: $30. A VeraLite-G (eBay make an offer): $135. A Z-Wave thermostat (2-gig CT100 that can display humidity on the main display): $80 (I got a couple for $62 on sale) No dependency on Google to control your home: priceless. Disclosure: I use MasterCard sometimes.
- watty 13y agoAre you trying to say that those parts are equivalent to a Nest? That's like saying some wheels, an engine, 4 doors == BMW.
- joezydeco 13y agoHe's saying it's functionally equivalent. engine + 4 doors + wheels = working car. I owned a BMW once and you literally could not tinker with the car yourself. The engine was a sealed black box. Kind of like the Nest.
- vicaya 13y agoI'm saying that you can put together a better (customized) system than Nest with these parts without relying on any external services.
- blueskin_ 13y agoShame Z-wave is horrendously insecure.
- vicaya 13y agoYeah, just like SSL :)
- vicaya 13y agoWhoever downvoted me, please provide reference. AFAIK, there is no weakness found in Z-Wave protocol itself but a specific implementation in a specific brand of lock, which is demonstrated by the z-force hack. The "just like SSL" comment is justified, AFAICT.
- SigmundA 13y agoI believe Nest motion sensors are what is referred to as occupancy sensors. They are simple and cheap infrared sensors that are not designed for accuracy but instead sensitivity, so they are prone to false alarms, which don't matter much if you're just averaging data or lighting up a display. Most motion sensors for alarms are dual infrared/microwave (requires heat and motion) to prevent false alarms. Even then it can happen. My dual tech pet immune motions at home connected to my HAI Omni have had a couple of false alarms over the years. Once due to a ceiling fan being on (tripped microwave) then some sort of heat event (sun changed through window quickly). Accurate motion detection for alarms is tricky, and requires very specific placement.
