Creating a custom HTML front end for Domotiz Part 3 – YouTube companion article

We’re going to get a bit more clever now. When we have taught Domoticz a list of devices (be they switches or lights or door contacts) we may want to list them all in one go without manually entering a long list of html for each device. Also, if we can get the HTML front end to gather all the information about each switch, it means that we can update the contents of the buttons automatically, for example if we change the name of a device, it will automatically update in the HTML front end.

I’ve created some code to do this and the commentary on this is over on my YouTube video.

Here’s the code and two css files that you’ll need. Please note that the css files contain more than is needed at the moment: however the css will be needed in future articles.
