Wife noticed the #cat 's #water #fountain upstairs was empty again this morning. It's not the first time, and this must be fixed, so I'm trying to sketch up a quick&dirty water #level #sensor to monitor with #homeassistant ...
The idea is to print it (in #petg for water resistance), place a #cherrymx #switch in the upper compartment and sink it in hot glue to avoid water messing with the switch. Then I'll connect it to _something_ (probably an #ESP32 or #ESP8266 with #ESPHome) and configure Home Assistant to issue a notification to my wife's phone when the switch is released (= the water level is too low).
