I wanted to connect a simple piezo buzzer to my 3D-printer running Klipper to make some beeps when a print starts, stops, etc.
Documentation of a point-of-sales display unit from GIGA-TMS INC.
This documents my personal findings, rom dumps, references to official resources available online, and working examples from investigations and experimenting. I got this device from a decommissioned grocery store cash register.

Information about Nexa AB distributed Z-Wave devices.
Please note that this document is a compilation personal notes and opinions about my experience (<1yr) with these devices (and not a complete list). Your experience may vary... and I would love to hear about it in the comments.
I created this because my meter doesn't have an accessible HAN port, and I was not able to find any basic Z-Wave sensor to monitor pulses that did not require the use of some (packaged) proprietary solution or a subscription (and mobile apps). Also, kinda expensive.
This cost me $50 in total (2023), which was considerably cheaper and very beginner friendly.
Accuracy is ~99% (when compared to billing information from my provider over a period of 90 days).
The "Nexa Bridge X" is a Smart Home bridge device. The internal name is "Bridge2".
There is now also the Bridge3, which seems like it's mostly the same as Bridge2 except it has a separate adapter for Z-Wave!
It can be attached to a home network and monitor / control devices via an App/Cloud or Local Web UI. Supports assigning devices to rooms and various automations via the provided firmware.
Since this devices comes with a (semi) open API and Websocket it's custom to create custom integrations.
Resolving the Low Voltage warning (aka the "lightning bolt" ⚡) on a Raspberry Pi.
Please note that this research was done on Pi 3 and lower. I don't own a Pi 4 which uses another USB spesification and different power requirements.
This is a document that was produced from a mess of personal notes in order to try to create a resource that might be useful for someone that runs into the same issues as me when it comes to powering a Pi in different scenarios.
