I’d almost finished writing out the most long winded post about not being able to get my new emonPi solar kit to boot. Tried everything, had the unit in pieces… nothing making sense, inconsistent problem solving results…
3 hours later, I double checked the power output of my USB port powering the pi… 0.7 amps.
Swapped it for a 2 amp… problems all solved.
So if you’re just starting out and cant get the emonpi to boot… make sure you’ve got a half decent USB charger powering the thing
