After various posts about using Arduinos etc to monitor damp/humidity over the long term I came across these in the Black Friday sales
Deal of the day: Govee Room Thermometer Hygrometer, Bluetooth Digital Indoor Temperature Humidity Sensor with Smart Alert and Data Storage
https://www.amazon.co.uk/dp/B086YYL439/
They arrived yesterday - breeze to set up and all the tracking, alerts and monitoring you could need. The company also make other smart things so would be possible to switch on a dehumidifier via a smart plug when levels get high etc
No connection just a happy customer
