i have 10 generic cams working with that so that definitly does work untill 0.82
the cams have there own tokens. not the one you create with HA.
this is a pic from 2 generic cams. and i never created any tokens.
and to access those cams i use
i can do that in a browser or in my dashboards without token, and it keeps running.
off course its possible they changed something after 0.82
the widget is just not setup to work with tokens, because at the time that AD was last updated we didnt know how to work with the tokens in js. thats why creating tokens will not work.
the url you give in the dashboard must be a valid 1 and it needs to work in a browser also.
