Review on π Wireless RF Relay Remote Control Switch, QIACHIP 12V 1CH 433Mhz Momentary Light Transmitter with Receiver (1 Relay) by Ben Rodriguez
Great fix for broken garage door opener
I bought this to fix and aging Craftsman garage door opener. The remote receiver is starting to malfunction, it opens the door just fine but will not close. I use this Wireless Relay to hook up the garage door button and it closes and open the garage door just fine.Pro tip: carefully uncurl the antenna to get even greater range.
