I purchased the YC9333 model in April 2022 which has a display showing the time via the wireless radio beacon in Cumbria. I also shows the barometric pressure and an indication of forthcoming weather which I have found 90% accurate. This model has 3 wireless sensors showing temperature and humidity. I specifically bought it to place one sensor in each of my fridge and freezer and one under cover facing north east outside. It has an internal temperature/humidity sensor for the room. The LCD display has a button for a light which goes off automatically. There is a memory button which shows max and min over a 24 hour period, resetting at midnight each day. Everything is powered by AA batteries and they lasted for over a year. I can see at a glance my fridge and freezer temperatures for reassurance on an old fridge freezer. I bought mine from Amazon and I am really pleased with the quality and accuracy.
