Why would you use a Play Store account from a country/region other than your own? Actually this can be fixed easily when you switch to the correct account. 

I can't help but feel (and don't take this the wrong way) why arbitarily code the currency symbol in the Tapo app, to a completely unrelated value in your Play Store Account?

I don't believe that the 'currency' in the Tapo App relating to energy monitoring is anything more than a symbol, that is not in any way related to Play Store purchases. As such, there is no reason why it could not just be user defined?

Then again, maybe there is a good reason, I just cannot see it. 

+1 for allowing custom currency selection. There exist valid reasons for having a different/multiple currency payment accounts in the play store. I could go into depth, but frankly, this should be of no concern to TP-Link. As the OP has mentioned, this is an arbitrary pairing in lieu of a proper currency selector.

The TP Link app should not dictate the settings for the play store app, or any other app for that matter.

I suggest a quick forward to the product/dev teams, to bring attention to this. It's just a dropdown menu, grab the PR quick win..

  @Wayne-TP my currency is also US-Dollar ($) even though I live in Germany? I can't seem to change it either. How can I fix it? The country set in my Play Store is already Germany.
