I’ve been reading all I could on this site, and am attempting a custom build with a rpi3, rpi lcd touchscreen, AdafruitDHT22, and a waveshare relay board as a proof of concept.
I followed the manual software instructions and seemed to have all working until the autostart of the local hestia page.
After ~20 seconds the countdown page throws a popup that says
SecurityError: Blocked a frame with origin"file://" from accessing a cross-origin frame
Press ok button and the 399 sec count down resumes…
I verified that chromium was started in the openhabloader.sh script on boot, with the --disable-web-security flag that I thought would suppress that error. So now I’m confused.
I’m sure I’m missing something obvious, if someone could provide some suggestions on what I can check, I’m sure this is very close to being able to fully test and convince my wife it will be a better solution…
Thanks in advance for any advice,
