[Feature request] Option to show highest set temperature

[giovi321]

I have two different devices for two different radiators and one is slower to poll and receive information. For example: when i set 25° one device goes instantly to 25°, while the other stays for a few mins to 24°. Therefore, I get the average between the two 24.5°.
It would be great to have an option to show the max temperature set instead of the average of the two.
