No power value for Legrand power socket 067775/741811, strange firmware availability

[dragorex71]

I have 3 of this devices and only one shows power consumption.
Z2M is updated and it does not report available update for the 2 devices.
Currently they are with these firmwares version:

As you can see they are in different versions, the third device running firmware "01b" shows power consumption correctly, the first 2 on "013" don't.
How can I update those devices?

Hi, The firmware used by your plugs are really very old, you should plan to update them on the latest version, it should work better.
You can update firmware via OTA tab

Is there any trick to do so? Because in OTA tab z2m doesn't show any update available. Even if 1 device is with a firmware and the other 2 are with a different one

On OTA tab, you click on the cloud icon, tit check if update exist.
