A Pi Zero W consumes half a Watt when idle, and up to 1.78 Watt when running tasks or connected to peripherals. A Pi model 4 B (the latest model at time of writing) consumes 2.85 to 80 Watt depending on whether it is idle or working hard. Although Cumulus MX does not need to run 24/7, derived values like highest, lowest, average, and so on, will be more accurately calculated if MX is left running. Although the Pi is not the only small computer model available, it is probably the most popular and the easiest one to use if you do want to run MX all the time and not wreck the planet! | ||
