3 values ​​for some entries

[openKimchi]

In the Json object that I get via MQTT, I have 3 values ​​for some entries (env, home, fanrpm, comp, outside, liquid).
Why is this so and what is the current value?

the json looks like this:
{
"protocol": "S21",
"ts": "2023-12-11T15:50:00Z",
"env": [
21.98,
22.02,
22.05
],
"online": true,
"home": [
25,
25.12,
25.5
],
"heat": true,
"fanrpm": [
0,
85,
730
],
"comp": [
0,
2,
18
],
"outside": [
6,
6.07,
6.5
],
"liquid": [
33,
36.78,
40
],
"power": true,
"mode": "H",
"temp": 21,
"fan": "A",
"swingh": false,
"swingv": false,
"econo": false,
"powerful": false,
"comfort": false,
"streamer": false,
"sensor": false,
"quiet": false
}

The stats on that report are every minute (configurable I think) with min, average, and max. I think the manual explains that, but if I have missed it, I am happy to update it or take a pull request. There is an option to force it always to be an array and not be one value (when it has not changed), which again I think is in the manual.
