3) BLE 5 supports DOA, your light switches can accurately locate BLE trackers.ĪFAIK you can not buy a system like this yet. 2) BLE is dirt cheap due to every cell phone having it. Why BLE? 1) You can use BLE to set up the wifi on the switches (no messing with phone being on 5Ghz and switch on 2.4Ghz). The light switches can mesh if they want, but it is not required. The BLE devices will not mesh, they will just hook to the nearest light switch. That way they can be sealed and be water/humidity proof. You can build 10 year coin cell sensors using BLE. These BLE sensor will attach to the nearest light switch and relay onto the wifi network. Since you now have BLE in all of your light switches it makes sense to build BLE sensors. Those switches will also have BLE via chips like the ESP32. We are not there yet, but my prediction for the end game is wifi based switches everywhere there is mains power. That’s why I suggested going with less expensive Wi-Fi switches. That adds up for someone like Gareth who has 30 switches to replace. The downside is that you can expect to pay roughly $45 to $50 per switch if you go with Lutron, and you need a hub. They have a pleasing design and for lack of a better description, they just work. Stacey is a big fan of Lutron’s line of switches and I can see why. And if possible, we recommend waiting if you can: The first Project CHIP products are due out in 2021. So the recommendation is more a matter of future-proofing and less of saying one radio protocol is better than another in this case. And for now, Project CHIP is using Wi-Fi, Bluetooth, Zigbee, and Thread radio protocols. However, we’re starting to see light at the end of the tunnel for Project Connected Home over IP (CHIP), which we expect to bring scores of industry brands under common smart home standards. There’s nothing inherently wrong with Z-Wave in the smart home. While Vera’s smart home controllers are excellent, our recommendation is to swap out the switches with different radio technology. Gareth also uses Google Home and is wondering if he should replace all of the switches with something more compatible. He’s using a Vera hub with about 30 devices and some of his switches are failing. On our most recent episode of the IoT Podcast, Gareth called in to our voicemail hotline with a question about his older Z-Wave switches. This is me swapping out switches in my bedroom. If you own your home, go ahead and rip out those switches and replace them with something better.
