  1. Hi,

    I am looking for wifi humidity and temperature sensors( separate sensors) for a swimming pool application. I require two types of temperature sensors, one for ambient temperature and one for the water temperature to be installed on the water line.
    They suppose to connect to the existing automation system, therefore, they must be able to communicate with a third party control system through BACnet. I’d be grateful if you could propose a few products that can fulfill the requirement with reasonable pricing.



  2. Hi, I’m looking for something cheap to monitor hot tub temperature through WiFi during winter in case heater breaks so I don’t have to go out each day to verify its working. Something I could see on my phone phone, ideally on google assistant.
