Motion Detection with Amcrest

Image
The setup of the basic Amcrest Wifi camera does require a non-HA interface to initially set up. In my case, I used their app on my Android phone. My experience was straightforward - Add a Device, walk through their steps. Done. Adding it to Home Assistant was more interesting. This is added to your base configuration file   If you've read my previous entries, using the !secret can be skipped if you just want to leave the host IP, username, and password in your configuration file. If you don't care about motion sensor triggers, you can skip those last two lines. Once you restart Home Assistant, BackdoorAmcrest will be visible as an entity. What I wanted though - if there's something triggering the motion sensor...I don't just want to record it for later, I want to know about it. So I go to Node Red. Two parts: the trigger & the notification You'll notice "motion-detected" is a binary sensor, which means true/false. If you had set up the motion-detected ...

Adding a Nortek Z-Wave/Zigbee USB dongle

Purchased online for $50, the Nortek Z-Wave/Zigbee USB dongle seems like the easy way to add Z-Wave and Zigbee functionality to Home Assistant.  What is Z-Wave? It uses radio wave frequencies to connect to each other, in the 800-900 MHz range. This means it's not going to interfere/be interfered with, from your wi-fi network (running either on 2.4 or 5GHz). The Z-Wave devices can (but not all do) repeat signals, creating a Z-Wave mesh. It's limited to 232 devices, which is plenty for my purposes, but allegedly opening up to more as time goes on. What is Zigbee? It is similar, but uses the 2.4GHz range. Zigbee devices can also create a mesh, but due to a multitude of different implementations, one Zigbee device may not link to another brand's Zigbee device. Zigbee send messages faster, and can have 65,000 devices on the network...which seems like overkill. To Choose, or Not to Choose Rather than pick one, and be limited to one type of device - the USB dongle seems like a fai...
