Merging data for smart plugs

@dolfs, OK, so you built the original history in Sense via a HomeAssistant calculation using EP10 on/off data forwarded to Sense via SenseLink ?

If that’s the case, then you probably are a little stuck because the Emulated Kasa / SenseLink data is essentially the same as a smart plug history and they are not currently mergable with another smart plug history. I would add your specific onto this Product Wishlist item, and “Like” the original posting to continue to build the case for better smart plug history management features.
