Unishox2 VS Tasmota

Use some sort of short text compression like unishox2. This can reduce a sentence like the above to a hex string of efbfaf95c4ea327cb26bd7488419958d24d7970884201310a5. Each of these characters going from 0-f (0-16) can be represented in binary like 0000 to 1111 and can be represented as circles (if a circle is present, 1, if not 0). I thought of a space saving measure which would to be to have one set of 4 circles inside another 4 set of circles. Since a pair of hex values represents a single character for the output of unishox2, group of 4 smaller circles each inside 4 larger circles can represent a byte. Here is an example design for the example sentence. Perhaps the center could be filled with some sort of art work?

All of my office devices are connected to Sonoff S31 smart plugs, flashed with Tasmota on their own locked-down VLAN, and can be controlled via voice, Alexa, Tasker automation on my Android, NFC tags at my office door and various scripts triggered via my StreamDeck (on Linux). This all works fantastic, and I can turn on or off my devices, including my printer, when I start or end my day at work.

The best alternative firmware example for true IOT devices is Tasmota [1]. Erase manufacturer firmware for every ESP devices the day after purchase to avoid those careless manufacturer firmwares.

The ESP8266 based Sonoff S31 and ESP32 based Switchbot plugs, both flashed with either Tasmota or ESPHome, are my go-to options for US WiFi smart plugs with power monitoring.
