Yep, if you want to see instantaneously or averaged over time for stuff that varies like that I also recommend the owl meter. What I did was make a custom extension cord that is only about 30cm long but has an exposed loop live wire to latch the sensor around. Then if I want to measure how much energy an appliance that has variable draw uses I use that extension on it. So for instance washing machines and dishwashers vary their power during the cycles. With that extension it became easier to measure how much power a single cycle uses and hence costs me. Could also compare different dishwasher cycles such as eco mode verses normal mode for example.
