I bought a Tapo 110 today and have it set up in HA and announcing that the “Clothes dryer has finished” based on the power consumption data.
Using HACS, search for the “Tapo Controller” integration. It is the integration mentioned previously in this thread: https://github.com/petretiandrea/home-assistant-tapo-p100
Then add Integration, and Tapo_p100 should show up (yes it is called p100 but it supports the p110). This should then allow you to configure a device (you’ll need the IP address and your TP-Link account details).
Here’s a screenshot of the associated entities created:
And here’s a snippet from my automations.yaml to announce on my google speakers once the dryer has finished. It works but I’m still trying to tidy it up.
Adjust the times and the power above/below values accordingly. My dryer was running about 1600W.
NB: this is a minimal example and I am very new to HASS so take it as it is
