Reading a smart meter using infrared

I had a chat with ChatGPT and she told me that I could read my smart meter legally using infra red. There is a port on the front of the meter that does IR RS232 at 9600. A bit of research came up with a Vishay document that shows how to do it. Part of it says this:

"For pulse shaping and recovery, an encoder / decoder device, such as Texas Instruments TIR1000, is recommended. The front end including transmitter and receiver should be realized for example by the integrated transceiver module TFDU4101 or any other Vishay transceiver model."

That sounds a bit complicated, has anybody here done anything similar? I remember that one forum member was working on smart meters. It would be handy to receive real-time readings. I'm still trying to find the elusive  200+ watts that is burning away 24 hours a day.

How ironic it would be if it were the smart meter... ?

Hi,
Does it tell you the format, I have an Eco-eye and without knowing the format I wouldn't have had a clue.
