Smart meter is a chocolate teapot

Probably a month ago Siemens installed a smart meter. Since then literally zero functionality is provided. There are 5 floors between the meter room and my apartment. Was this just a box ticking exercise to appease the government or is there actually something wrong here?

When they installed my gas meter the chap said he doubted it would work from one floor difference - but then saw the meter was actually directly under my apartment. But 5 floors? Unlikely from what he told me.

The meter itself will work in terms of submitting readings automatically to the supplier. But an In Home Display will not work.
