DieseRC DC 12V 24V 4CH Wireless Remote Control Switch DC 6-30V 10A 4 Channel 433Mhz Radio Frequency Relay Receiver with 2 RF Transmitters for Lights Garage Door Motor Canopy

I used this relay box to upgrade from a clunky cumbersome remote to these compact fob style remotes. In my case it was easier to piggyback a relay with remotes already paired, than try to find a remote on the frequency of the old one. The old one was a custom built remote for a revolving stage, and I wanted to change the form factor, as the stage is not being used in a theater setting, but rather in a home. I've used a number of the two channel versions of this relay as well, to switch motorized drapes whose controls were once switched in-wall. The motor/track units were old Silent Gliss (from maybe the 90's), and these provided an easy way to regain control and modernize them, acting as simple dry contact relays. I'm just getting into "smart" home integrations, and it wasn't difficult to get those relays to integrate with Google assistant through the Tuya app. This relay, I don't believe has the same wifi feature, which would have been nice for me, but I bought it knowing that I could always piggyback one more to gain wifi based automations. So far, the remote works great and the relay is functioning flawlessly. I had to switch from latched mode to momentary control for my application, which I think I might have figured out through there instructions. Overall, I'm happy these things exist, so affordably, and in such compact packages. Will update if it quits working.

I used this as a remote control for forward/reverse on an outdoor model train. It works happily with a 6V power supply from four AA batteries. The two remotes were already paired and the unit was in toggle mode which is what I needed. All feels very good quality and robust. The wiring diagrams in the instructions aren’t a great deal of use, but it’s just four relays so hardly rocket science to work it out!
