Re: react app / revpi connect 4 / chromium

Hello cerberus78 Your report is comprehensive. Unfortunately, performance problems are always difficult to deal with.

Du kannst das Video anschauen für die Inbetriebnahme: https://www.youtube.com/watch?v=EF-Jtd6mP...

Nach etwas grübeln, fallen mir zwei Dinge ein - schaue dir die Seite der Knowledge Base an Commissioning RevPi AIO Prüfe die Verkabelung, denn das AIO benötigt stellenweise Drahtbrücken. Nach dem Ändern der PiCtory Konfiguration muss die Konfiguration gespeich...

Re: Effect of interruptions in power supply

Hello Pedro, I read your request with interest. There are already some discussions here in the forum, e.g. here, whether a simple capacitor can also enable this functionality: https://revolutionpi.com/forum/viewtopic.php?t=1416 A further discussion raises these questions as to whether the file syste...
