Have an off the shelf atomic clock (syncs to atomic clock radio signal) with outside temp sender. Replaced batteries and now the unit is acting crazy. Have pulled the batteries overnight and tried again but same results. Our previous one lasted longer (this one is only about a year old) but it quit after a few years. Thinking I could display time and temp from the web on a tablet. Somewhat more than a replacement clock but lots of flexibility on what I display and could even have on screen buttons for control of things with a bit more work. Someone has probably already put out software to do this. Or is there a better alternative?
