@caseyliss @marcoarment so you’re saying your water leak sensors are cheap? These ones from Ikea are ~10$ (1$ used to be > 4 zł, now it’s ~3.5). They’re based on Zigbee so they have very low power consumption (I have other leak sensors that have been operating in CR2032 battery for at least 3 years). This one uses AAA battery and has a built in speaker. Works with Home assistant too.
