I want to use the Custom HTML Dashboard Block to show live data coming from a simulated MQTT device. However, the block does not refresh on new data. I am using the default block html code to test it out and it does not refresh. It just shows the load time value.
As you can see in the screenshots, I am using the default code in the block. When I use the Indicator block to show the same data, the value does update. As far as I understand, the ‘change’ event should trigger on all changes, so shouldn’t the block output also update when new data arrives? Please let me know what I am missing.
My aim was to use Google Charts to display the values in a gauge. However, I found that the gauge does not update (using the code given in your examples). Then I saw that the default code also does not update.
