A Cloud-Free, Plug-In Solar Plant

A Cloud-Free, Plug-In Solar Plant

Over the last year I had started to take an interest in plug-in solar power plants and finally got my setup working in June 2024. However, one thing that always annoyed me was the need to use the manufacturer clouds to control the setup. While I get the pros manufacturers see in forcing use of their cloud services, I find it deeply unsettling for a variety of reasons. Most importantly because they are not a technical necessity, but instead present a possible source of errors.

Smart Home: Shelly BLU Door/Window integration to MQTT without a dedicated Bluetooth Gateway

This article is purely for informational purposes. I’m not promoting any products or trying to sell anything — just sharing my findings and learnings.

As somebody who considers himself technically interested and strongly in favor of privacy, I have absolutely no tolerance for any cloud-connected devices if I can avoid them. Consequently, none of them have internet access and everything must work locally. Shelly devices have always been an easy choice for me, as most (if not all) of their products support local-only configuration without prices that lead straight to bankruptcy. Seriously, thanks! I really appreciate it.

Introduction

The estimation of wireless channel parameters is an omnipresent task in many application of wireless propagation, for example communication, sensing, and channel sounding. Due to the variety of applications, different solutions have been presented, usually engineered for the application-specific constraints. Lets look at the three example applications in more detail:
