Domoticz part 8 – Stable instance of Domoticz, 24/7/365 mode – high availability at home

Is there a simple and effective solution to increase Domoticz’s availability on Raspberry Pi / Orange Pi? Sure there is!

With a quite decent resolution of 128×64 and based on OLED technology this is a nice 0.96 inch display. Well, my first computer was running at Hi-Res of 640×400 and monochrome too. Priced at $3-$5 pops-up…
