Sends temp. to my phone.

I’m using these in some custom house temperature sensors, both inside and outside. Three are used in my outdoor heated cat house, for our unfortunately outside cat. I measure air temp, the heated bed, and ambient cat house temp, and it just works. It’s been working for 9 months without issue.
