well. I changes my real cameras to use stream_source: instead of input: and not the problem with the EC radar has gone away in HA version 0.90. using env_canada 0.0.8 . Don’t understand the relationship but seems to be a conflict with 0.90. stream to chrome cast function added in HA 0.90.
Just got HA 0.90.1 and everything looks good.
PS. Used Stream Component: Confirmed Cameras and Configurations to find correct streaming settings for my cameras.
