Air, temperature, and the power a room actually uses.
A CO2 meter turning amber at 1,000 ppm has not caught you crossing a health limit. What the reading says about the air in a home office, where the 1,000 figure came from, what the research on concentration shows, and what to check before you buy a meter.
A room that stays occupied all day adds up: a monitor and dock on standby, a heater on a timer, a window that stays shut because it is cold outside. This category covers energy use, power, and indoor climate.
On the energy side that means smart plugs and energy monitors, standby consumption, and what a device draws according to its own specification. On the climate side it means CO2, temperature, humidity and air quality, the sensors that measure them, and what a reading does and does not tell you.
We keep to what can be measured or looked up, and we say which measurement a recommendation is based on.
