Wifi relay power switch




















I had the same idea but made it dimmeble also for LED bulbs. Question 3 years ago. Does know what fllavor of Panasonic varistor was used on rhe project, there are many and I obviously have the wrong one Lotts of blown fuses.

I'm wanting to do something like this, except that the 30A relay needs 12VDC to switch. Reply 4 years ago. I'm curious why I can't find these on Digikey or anywhere else besides ebay Hello, I don't know much about the BPB12 but it looks like it should work. Just don't forget to update the pcb since the pitch is not the same.

Or the hlk-pm12 is ok too. The LDV33 can take up to 15V dc and convert it to 3. Best of luck, and please keep me updated about the result. Cool project. Some savings might be to use breadboard instead of the cost of plated PCB. Do not see need for terminal strips, just solder directly as you are not interfacing to other projects.

As suggested to put IN diode and maybe capacitor of small value to remove spikes, which could kill the transistor. Stripe end to positive voltage feed. If there are 2 outputs, how about adding second relay, resistors, diode and transistor to have 2 outlets thus able to control 2 lamps or devices at same time. Adding a fuse to the output to prevent overloads and for safety. If space is not a consideration, repurposing a cell phone charger works great for a source of 5 volts and also may provide a led to indicate basic power.

Can the software be made for time delay? That would be useful to make it serve as a entry way lighting, or sleep timer for any room. Thank you so much for your comment. I was not sure if a breadboard could be used with voltage as high as V. Using the 2nd output of the Esp for another relay is possible and is a good idea. And if there is a power failure, I'm not going to be able to turn my light on anyway, so I don't care if I cannot control my board.

Yes the software was made for time delay. The rtc is provided by the blynk server, and the time information is sent from the app to the board through virtual pin v3. Great product i make an wall outlet with arduino pro micro 2led and bluetooth hc and one relais. But you idea is most powerfull. Great diy with esp I am debutant in arduino and electronics and the esp is more complicated for me at this time.

But i will made your idea after. Eye blink on switzerland connector outlet. I'm working on a similar design and added an override push button switch. It works but has issues I hope someone can help me with. However if pin 0 can see gnd at startup it goes to programming mode. If I manually disconnect it during startup an then plug it in all is fine. My question is there a technique or device that would caus the pin to "float" for a short time milliseconds I'd guess then connect?

Thanks for any advice. This is an interesting question, I think it has been discussed on the esp Nice little design,.. Thank you for your comment. I didn't know about transients. Do you think that this protection might already be included in the relay board? You may be correct,.. Wireless Remote Control. Bluetooth Remote Controlled Relay Devices. See all Bluetooth Relays.
