data from MQTT: [“2018-11-21 13:39:21”, ‘test’, 23.6]
However, when data arrives, the sensor registers them, but the graph remains empty.
Sorry for my bad english and bad code of configuration.
I found solution.
In my case value_template: “{{ value_json[2] }}”
Problem in quotes ” . I replace from ” to " and all values become float, not string.
Using history graph and MQTT sensor, would it be possible to make a graph for the following day for instance?
In my case I get electricity prices per hour one day in advance and I’d like to plot that in a graph.
With your sensor do you supply it with time as well, or is the time stamp automatic and not changeable?
