Temperature sensor diagrams not shown

[clafib 3]

I have 9 motion sensors, and of these only 3 do not have temperature graphs.
Analyzing the versions of all the sensors, I realized that those that do not display the temperature graph (the three mentioned above)
,have a version 2.8 (and 3.67 zwave sdk), while those who view it have a version 3.2 (and 4.5 zwave sdk).
Do I have to buy three new motion sensors to get the temperature graphs, or can the firmware of these three be updated somehow?

@clafib All of my fibaro motion / temp sensors are on firmware 3.4 and have the temp graphs

 

Move them close to your homecenter 3, if this is the master hc in your setup, than check if you can update them under:

Settings > Devices > updates

No, no updates available, I checked.
But if I buy 3 new motion sensors, what do I have better than having the temperature graph?
I'm trying to justify the cost of 3 new sensors...

for he differences. The newer firmware supports Nr 4 + 5 associaton groups and better security.

 

Did you try soft reconfiguration before the firmware update?
