hi Wijnand, which battery/panel/charger do you use? sorry if I missed that information. Sounds nice, but at the moment there is an electrical noise audible. Sounds to me as if you use Primo 172/272? You can try to move the mic cables and/or wifi hotspot, that has helped often in my setups with these mics. Or use AOM5024, they work better with the Pi Zero. bests, Udo

The stream is permanently on, depending on how long the solarpanel-battery combination will lasts. (and data :))
My calculation gives a good result for the period from March to October.
