I plugged a tapo P110 smart plug to water bowl's pump to track the usage. I realized when water level is low wattage decreases by about 0.1 watt. Surprisingly, smart plug is sensitive to those changes and shows the difference in HA. I have created an helper to average last 10 minutes of data for a more smooth data.

Now I am notified when the water level is low or empty. This is no way fool-proof or reliable way to track the water level but it helps.

Here you can see the dip when water level is low and after I filled the bowl
