LF: Aquarium (Zigbee) Temperature Sensor

[sly wyvern]

Anyone know a (cheap) zigbee temperature sensor that i can use to measure water temperature in my aquarium?

Alternative would be a submergeable sensor i could use with esphome

on the esphome front you could use a waterproof ds18b20 wired to an esp32. only needs 1 resistor to work nicely
