Review on π Wireless RF Relay Remote Control Switch, QIACHIP 12V 1CH 433Mhz Momentary Light Transmitter with Receiver (1 Relay) by Arunprasath Elliott
Great single channel RF remote.
Fast fix for a 22 year old lift master that the Rf quit working on, just need a 12v dc supply and yer good to go. Paired the two remotes and set it up for momentary operation, easy peasy. Not the best for security but until I take the opener apart and troubleshoot the control module suffice it will.You can even swap the little circuit boards from the remotes so it will clip onto the visor or whatever.
- The programmable rf transmitter and receivers can be flexibly configured in quantity and in operating modes.
- It is not energy-efficient
