Update shelly h&t do or don't

i have two shelly h&t wifi sensors underneath the ground floor for measurements.

Both sensors have a firmware update waiting.

But it says that i should not update if i csn not get to the sensor easy. I guess because an update can in some cases cause isues and then you need to get to the sensor?

My question is, how save can i install the firmware update without having to get to my sensors? What is the chance of succes?

Understand that getting under the floor is not easy for me.

What are the consequences when i don't get firmware updates??

Thanks in advance.

Hi,

Both Shelly's are usb powered.

They are on the home network with a static ip.

I only use the shelly cloud app, or get to them trough a browser using their ip.

Hope this imformation helps.
