DSD TECHSH-BTx04 4 Channels Bluetooth Relay Module Remote Control Switch Compatible iPhone Android 4.3 (12V)

Brilliant idea, i have this set up to control the amber strobes remotely from my phone when I'm out of the vehicle, may well get a six relay version or bigger for more controls.

I am giving 3 stars because the switch lookswell made. Maybe I can get it to work if I use an old phone but it won't be very convenient. The description says the app works with Android 4 or later. I have v13 on my phone and the phone says the app is incompatible.

I use this 4 channel bluetooth relay in my truck. I absolutely hate having switches in random spots all over my dash, and this takes care of that for me. No switches on the dash and no mess of wires running through my firewall. I used an add a fuse on a circuit that is only on when the key is on to supply power to the board. That way someone can't walk by and turn the relays on when the truck is parked. I have the boards relays wired to four 40 amp relays to control a transmission cooler fan, a light bar, a fuel transfer pump, and an extra if I add something down the road. I modified a thin tool case to protect it from moisture and weather and mounted it under my hood. I have had no issues with it. It's been through negative tempatures in the winter and through the hot days of summer and has not failed. It has also been down some rough jarring roads and not failed. If my phones go down there are buttons on the board to manually turn on and off each circuit as a backup. I have an Android phone and an iPhone. Both pair quick and flawlessly every time. I'd highly recommend this bluetooth relay and the DSD Tech Bluetooth app. I also have the DSD Tech 2 channel version in a different vehicle used in the same way. It's also been tough and never given me any trouble. I think I'll buy a couple more for projects around the house. These bluetooth relays are amazing!

2 relais qui étaient HS Module renvoyé, pas de nouvelles.??

Mi sarebbe piaciuto trovare questo prodotto con più canali e non solo 4

Alles super!

I only tested it just after receiving the board. It worked with the directed app . I have not connected to the device I wanted it to control. To hot to work in the 90 degree shop lolIt’s a very nice unit
