That is a great idea!! Why not post all our favorite program action steps when using this controller? Anyone else want to share screen captures of their program action steps?
So we have Lightning and Fireplace from @erocm1231 Someone come up with their favorite Police, Christmas, Party, etc effect? On my SuperNight controller it had a couple presets called Fade3 and Fade7 that were kind of cool for just showing off the color range capabilities.
Here are my Police Lights or should I call it Dance Party? it’s a tough call
@michaelahess got a simple question. I want to drive a high amp relay from any spare channels of the H801. I don’t want to mess this Sunfounder relay board up that just came in today. I was going to originally just run the VCC , In1, In2, Gnd right from the H801 but before I did I saw this detailed info about the Sunfounder relay I got. and I wasn’t understanding without doing damage. Not sure why there was a J5 jumper on only one of the inputs? Can I use the 12V that is coming off of VCC of the H801 that powers the RGBW strips into the VCC of the dual relays?
You can use the 12v out from it but if using a relay why not power the h801 in parallel, then just have the 5 channels function as the relays trigger? Amp draw through the device would be my concern, and negate the actual purpose of the relay being that is high voltage. Or I don’t fully understand your use.
It would appear that relay requires 5v on the trigger so you would only pass about 40 percent on one of the channels or risk overloading the relay. A custom DHT that only allows a power state at that level would be recommended. Test with a multimeter first if you plan on doing this.
Thanks Michael. I wasn’t sure if putting 12v on that relay circuit board was going to hurt that circuit. I tried to use the 3.3v from the H801 board and nothing happened (I assume due to the voltage being too low)
My use case is I need to get some dry contacts for operating an up and down lift. Instead of using two separate z-wave relays (expensive $75) to operate the lift I wanted to use an H801 triggering either relay. For about $20 I get two independent outputs that I can control (MUCH less expensive)
You dont need those boards, they have a transistor on them to drive a relay from the gutless output of a microcontroller. The 801 has 5 even bigger transistors in it (mosfets) to drive many amps worth of LEDs.
Just get 12v relays and put them on the output of the 801, you will need to add flyback diodes to them to stop the kick when they switch off going back into the 801. I will dig up some links with schematics to post later on, but pretty much any 12v relay will be fine once you put a diode across the coil.
You can have dry contracts by cutting two traces that are on the edge of the pcb and are separated from the rest of the PCB so wouldn’t take long to do. Then a wire to connect the cut traces to ensure that the screw terminals are connected to the relay.
EDIT: Take it back, the wire is a bit more awkward as the trace to cut is less accessible. Let me check the PCB when I am home to give you the easiest instructions.
Ok, so here is the image of where to cut and add a wire. It isn’t an ‘easy’ cut as it is quite tight. However the black box is where the relay is and red box is the bit that needs to be removed, while the blue bit is a new wire link you need to add. This will make the Sonoff have volt free contacts.
The key thing to check after you have cut the PCB is that there is no connection between 2 and 3, but there is a connection between 1 and 2. I have shown the top of the PCB so you can see which trace needs cutting. A small hacksaw would be perfect, just go slow so that you do not tear/cut any components. The result is you have mains in on one side and volt-free on the other.
It shouldn’t be too hard, but if you don’t want to do it then the only other option is to buy a separate 3V3 power supply and connect to the breakout pins (used for programming) and then you only need to cut the tiny trace to the left of 1. Do not do this unless you have a 3v3 power supply!
Ok no problem, the same applies but it is even easier since the trace you need to cut is more accessible/visible. You need to cut the bit in the following image, in the same way as above
The only difference is that you need to cut less of the PCB in order to break the connection between 2 and 3. Using a sharp-ish hacksaw will carve through solder with no problems as it is so soft, so that shouldnt make a difference to the process. After completion you should see that the two screw terminals on the right are either disconnected or connected depending on the switch status (and no voltage will exist there) - maybe check with a multimeter first as I cant see the top of the PCB, though 99.99999% confident the above is correct.
one of my H801 unit stopped working. well I was not using it to be frank. I bought it, flash the firmware from Eric as in first post, tested it and stored it as backup.
Now when I wanted to use it, I tried power it on.
When attached with 12V power, it only green LED is on, red LED is very faintly on which you can see only when you remove the cover.
Device doesn’t get detected/discovered in app, I’m not sure if it’s connected in wifi network or not.
it doesn’t start with it’s own wifi hotspot as well.
Can anyone suggest what could be wrong about this unit?
Is there a trick I might be missing to get the virtual switches working? I see the switches under my list of devices, but nothing happens when I press the one that I programmed.
Here’s what I’m doing:
-Go in to the SmartLife SmartApp and select the device I want setup a virtual switch
-Select programs and made a simple program with 1 action - fade to red, 10% level, no duration
-0 times to repeat (I want it to come on and stay on)
-Hit done multiple times until everything is saved
The virtual switch I just made will show up under my devices, but doesn’t turn the light on. At first it did nothing when I turned the virtual on/off. Now it will shut the light off if it’s already on, but will not turn it on.
