Figured out how to download all the data and started with the energy pal site, the Electric Ireland plan is still coming in at the best 24hr unit rate plan based on the info I have supplied.
The majority of my energy usage is during the day time as I WFH so a time of use tariff is no good to me as all the washing / dishwasher / dehumidifier and cooking (this changes based on husband shift to more peak times every 2 weeks of the month) is done from about 9am until lunchtime so the cheapest electricity during that time is what I need.
