Hi, I’m new to HA and just ‘installed’ a Tapo P115 Smart Plug for controlling my water heater.
All went fine for adding the device, except that some measurements are not what I expected 
Looks like the ‘Total Consumption’ is always giving the today’s consumption and not the “grand total” …
Can I alter this? Like I said, complete noob on HA, I am a developer so I know my way around in scriptiong and programming environments
Tx for the help
Hello and welcome to the forum!
Yes your Tapo device measures both the power (W) and does its own calculation for the energy used (kWh).
This totally avoids any need to convert power to energy, and we should be able to use both the daily consumption figure, and the total consumption figure separately. The plug device resets the daily consumption every day, based on the change in the total figure. Neat stuff!
I have a couple of P110 devices, but not in active use so I can’t check my figures, however the Tapo app shows both power and energy, for today and in total, so the figures should be good.
First step would be to check on your Tapo app to see if the device is recording power and energy correctly. If on Tapo the total and day figures are the same, Tapo might not be set up correctly (needs location timezone to know when midnight is for you to restart the day figures)
Then check the integration. There are several, I’m now using Tapo smart home but that does not appear to support P115. The integration may not be pulling in the correct figures.
Then (clearly) check that you have used the correct entities in your card. You might just be using the total for both.
Hope this helps!
Oh and I should have said right at the start, if this is the very first day of using the Tapo P115, then yes clearly the today figure will be the same as the total!
Hello, did you solve this? I have same problem with daily and total consumption…
