Does the PI have any kind of 'deep sleep' support? If you could put the system into something like ACPI S3/S4 sleep state (suspend to RAM) and make it periodically wake up every n seconds, you might be able to save a lot more power. The PI would still be usable for many tasks, e.g. data sampling every few seconds.
- geerlingguy 11y agoI've been looking into this; besides people calling me a 'noob' for not knowing how to do this (but not offering any suggestions as to how it' stone), I haven't seen any way to put the Pi in an official sleep mode, short of buying a Sleepy Pi hat that basically runs a lite Arduino as a hardware power management layer on top of the Pi.
