No rocket science tonight. Just some easy hacking.
I finally root caused the Z-wave device interview failure that I was facing. The failure was due to a defective daughter board from zwave.me. I finally got around to trying out the replacement board tonight.
I also resolved networking issues on my Raspberry Pi. My home router (a very basic one that I've had since college) doesn't support port forwarding to DHCP clients. I will need the port forwarding to control my HAN from outside the home. The workaround was setup the Pi to use a static IP. The router supports port forwarding to static IPs.
It is work in progress to schedule in a weeknight to work on off-the-clock projects. I hope to resolve this soon (requires coordinating with the wife). The other issue has been lack of air conditioning in my office (aka. uninsulated garage).
