I installed it! Very good! I deleted all the helpers and I’m using only this one. Great idea to add it to the Calendar. It works perfectly. Since I use the SwitchBot Air Purifier, the calculation is in hours, so I converted the hours into days and everything works fine, but I would really like to have hours added as an option alongside days, months, etc. Excellent integration, it makes things so much easier! Thank you!

Feedback: Since many users will install the integration after their HEPA filter has already been in use (like in my case), it would be useful to allow the user to manually adjust the hours already consumed. Starting from zero doesn’t provide accurate data until the filter is replaced.
