Review on ⏲️ MakerHawk Time Delay Relay: 12V 5V USB Controller Board with LCD Display for Delay-Off Timer Control Switch by John Milligan
A versatile device at a great price!
I bought three of these gems to control my chicken coop and they work pretty well except the timing circuits are pretty inaccurate! In a 24 hour cycle (1440 minutes) he gains 21 minutes! Still playing with it to get my 24 hour cycle. Once you understand the programming, you will see the power of this device. Apart from the sync problem, a very useful little device. UPDATE: After some experimentation I was able to get the correct time for an actual 24 hour period of 1417 minutes instead of 1440. This explains the extra 40 seconds that the timer circuit adds for each hour. Once you get that, it's great!
