Looking for some ideas:
Problem - greedy dog is fanatical about getting to 1st floor landing where the cats are fed, what I need is something I can hook to her collar to trigger a sensor when she get halfway up 1st flight of stairs - I have found a couple of shortrange rfid setups - one looks good - but the range is 4 inches - another is a possible but it's a metre range with the right tags and antenna that will fail WAF if bolted on the stairs
So - small/discrete won't trigger when we or the cats walk by but will allow me to set of an alarm or when she tries.
