Temperature messurement

Hi Guys,

I’m searching for a thermometer that I can use to measure the temperature of my whirlpool. Right now I’m using 833MHZ Homewizard Thermometer but it has no good Homey integration.

Requirements:
Water Proof sensor
Graph inside of the homey app
Resolution of 10 Minutes or less

Any hints?

One hint

I use a 433mhz temperature, humidity sensor with external sensor.
Something like this

Can be used with this app: Draadloze Weersensoren App voor Homey | Homey

Fibaro Smart Implant with a DS18B20 attached.
