Hi there! 
So I feel like Iām super close. Iāve included everything you recommended (a timestamp is now sent with the path in a JSON MQTT message) and in a way it sort of works.
Weirdly, however, the first time the lovelace page updates following the sensor changing/updating, you get a broken image. If I then refresh the page, the image then loads fully. Thatās odd. Because itās like everything is in place for it to workā¦and it doesnāt for some reason. Thanks for your help. Not sure if @Mrianphill had to counter this problem somehow??
Cheers guys
