Octopus energy and entities

Hi all and firstly thanx for all your wealth of knowledge and time to make HA what it is. That said being new to HA I’m on octopus energy and have a home mini. I have the integration set up but have been given the list of 99 entities all with various names. Some show up in different lists when trying to get these into the energy screen.
I understand the various symbols £, electricity symbol but I’m struggling with which ones to use as some cause conflict warnings, some seem to do nothing. Please is someone able to give some guidance as I thought the home mini gives 5 and 30 minute responses. Cheers in advance
