Review on 🚫 Honeywell Transmitter: Limited Stock Alert - Discontinued Model by Honeywell by Adam Walsh

These little guys are very small and compact. It was very easy to program them. A few things to know: After inserting the battery, blue and green LEDs indicate when you have contact with the magnet and when it is sending a signal. The light goes out after about 15 minutes. They should also be able to show a red light when the battery hits a certain threshold and needs to be replaced. I've also seen some discussion about which loop to use. You're using loop 1. If you let the keyboard read the serial number by passing it in, it should automatically read loop 1, but if it doesn't, you can change it manually.
