Openhab, Grafana & InfluxDB2 - State Timeline & Status History for Simple motion sensors
Hi i was hoping someone could help a newbie out.
Im playing around with Grafana trying to make a “graph” that looks like the following:
Link to this here
For example the query i have is the following:
from(bucket: "openhabdb")
|> range(start: v.timeRangeStart, stop: v.timeRangeStop)
|> filter(fn: (r) => r["item"] == "Room1Eye" or r["item"] == "Room2Eye")
|> filter(fn: (r) => r["_field"] == "value")
|> map(fn: (r) => ({
_time: r._time,
_value: if r._value == 1 then "Detected" else if r._value == 0 then "Not Detected" else "Unknown",
item: r.item
}))
Its pulling the necessary data and all seems ok, i can see it, like so:
But i cannot make the visualization the same as in the example above! I try for many hours and i cannot get the blocks to be wide like that, i dont want those thin lines, even though the sensors catch for 4second movements.
I know there was a way to do it with the Discrete Panel, but its discontinued.
I have more sensors to add later, but im trying 2 for now. Also if the one sensor gets no movement for the 6hr chart, the whole sensor disappears from the chart until there is movement.
If anyone can offer a more efficient way of my query as well, that would be great.
Please someone can help me? I appreciate it
