Linkquality of routers doesn't show as graph

[h4nc]

I noticed that the linkquality isn't shown as graph in home assistant. Looks like homeassistant takes the state as a string because every number gehts its own color in a bar (see picture).

Thanks, fixed

@Koenkk I have zigbee2mqtt edge. Do I myself have to change something too fix that in HA, but for now I see it like before.

[Koenkk]

Update to latests edge and restart home assistant should be enough.

After reinstalling edge the linkquality shows as graph.

But now I noticed that it says
Linkquality: x RSSI

RSSI isn‘t a unit and also we get values for linkquality AND RSSI

[Koenkk]

So in order to have the graph shown the sensor should have a unit, what would be a good unit for the linkquality?

[h4nc]

I see, so we need to set a unit so that the graph is shown. Isn't there a way to set it unitless.

There are some value in physics that don't have a unit like the Mach-number.

If it's not possible to set it a unitless number than your solution to set it as RSSI is good enough until there is a way to set it unitless.
Maybe something like that should be implemanted in ha, unless it it isn't already.

Do you knwo which units are allowed in ha?

EDIT: Or maybe someone can tell the unit of the linkquality. Unfortunately it does seem like it is percent.

@h4nc there isn't really a unit, https://www.avrfreaks.net/comment/1162131#comment-1162131

@Koenkk I suspected that. So it's like the mach-number a unitless number.

So "right" way would be to have a unit "unitless" in home assistant. What do you think?

[Koenkk]

yes, updated to -

[h4nc]

I updated edge and the unit is gone in the attributes but I still get the unit RSSI in the state.

[Koenkk]

Did you restart home assistant?

[h4nc]

Yes, I did. Tried it again, still RSSI
