Re: Sensair S8

I would simply hook it up via a breadboard and see what comes out.
I am running several S8's, both onder Tasmota and ESPEasy. Nothing special needed, the sensor spits out values almost immediately.

Re: Sonoff 4CH suddenly half-dead!

An empty capacitor acts as a short circuit when charging, starting at 0V. So increasing the capacity will also draw a high current for a longer time. Often there is some resistor in series with the capacitor just to limit the peak current. But its max. power dissipation is designed with the 3.3uF c...
