On the way to HA with 3 Tasmota Sonoff bridges to control shutters and blinds on floorplan with picture elements cards.
From the age of 6502/Z80/assemblers and opcodes I now find myself in what seems a very very steep learning curve of Home Assistant.
Installed and running well on Raspberry Pi 3+ but any attempt to proceed into examples for cards i.e. custom compact header etc. fails with red error windows “card doesn’t excist”, “card not found”, card ïnvalid" etc. I access HA via Windows 8 with Chrome browser 74.0.3729.169 , purging caches via F5 and F12 has not brougt any changes.
Do all cards per haps have to be referenced in resources ui-lovelace.yaml and how does one do that card-modder or something like that.
The learning curve cannot be that steep, what am i missing?
