Then if you look under Settings->Devices&Services, you can create a helper using "intergral sensor". Point it to the "sensor node" for power you created in node red and it'll do the accumulation of Wh for you. The advanatge of this is that home assistant already has a way to store the values of these helper variables in it's infrastructure, so these accumulated numbers survive a reboot. Previously , I had been sending values from node red out thru MQTT and looping them back in to home assistant... but that is clunky.
