Users should upgrade the firmware on all 700 series controllers to version 7.17.2 or greater. It appears that this bug is largely, if not completely, resolved as of firmware version 7.17.2. At present, all 700 series controllers share the same firmware and are subject to this bug. I will be updating this article, once it makes an appearance on Amazon.Until recently, 700 series Z-Wave Controllers had a bug that could cause the mesh to be flooded on some networks and the controller to become unresponsive. Currently, it is available at CanaKit, SparkFun, and MicroCenter. Overall, the Raspberry Pi Zero 2 W, is a fantastic upgrade and is perfect for those wanting to run room-assistant and some other applications 24/7. The Wi-Fi connection should see an improvement thanks to the new enclosure which improves RF compliance, but is still only capable of Wi-Fi 4 (802.11n). There are 512 MB of RAM available, two Micro-USB ports (one for data, one for power), a Mini-HDMI port, a MIPI camera interface (CSI), and a MicroSDHC slot. The rest of the specs have been left untouched, which is what you would expect for a US$15 computer. Unfortunately, Bluetooth 4.2 is quite dated at this point and I would have hoped to see Bluetooth 5.X to increase the range of my room-assistant nodes. Other spec bumps include Bluetooth 4.2 with Bluetooth Low Energy instead of Bluetooth 4.1.

While the cores in the newer model are almost ten years old, they are a significant upgrade. A total of four ARM Cortex-A53 cores make the Raspberry Pi Zero 2 W's system-in-package, which is the most significant upgrade when compared to previous models, which only had a single ARM11 core.
