RANet relay expansion not working

[grafxalien]

I tried to hook up my ranet relay expansion today. None of the outlet seems to work. Even when I set them to always on. I flipped the 1st switch on. 2 and 3 are off on the side. Also, there are 2 ports that I cant plug anything in to because the copper inside is bent. Is this fixable?

here is my code:

You should leave them all off (up position) That's the id for Box1

[grafxalien]

thanks, that fixed it. I used a small screwdriver and was able to bend some of the copper in the two outlets the didnt allow me to plug anything in. That seemed to fix it. Still a little rough plugging things in them though

[grafxalien]

another question about the expansion. I just go back in town after getting it setup. Last night I noticed that every 10-20 min my refugium light would turn off for a second then right back on. This light is hooked up to the wireless relay expansion. I think the expansion is losing connection to RANET, turning it off then back on. The box is only ~3 feet away from the controller. Is there any way to check/fix this problem?

[rimai]

That does look like loss of connection.
The way the loss of connection is handled right now is if the module does not receive data for 2 seconds or if the data gets corrupted over the air when being transmitted, it will assume loss of connection and will enter into fall back mode.
Maybe we can increase this limit.
The only problem is that it is not easy to reprogram the firmware of the box.
It requires disassemble of the box to pull out the RANet receiver module inside of it.

[grafxalien]

does a re-program require it to be pulled out and sent back to you?

[rimai]

The reprogram can be done by you if you are willing to open it up and try.
I'll put together some instructions shortly.

[grafxalien]

i have some time off this weekend so I could give it a shot as long as I don't need any special equiptment

[rimai]

Open the enclosure box
Remove all screws to free up the board inside.
You should be able to pry the board from the outlets.
Pay attention to the Logo LED lead wires. Make sure to disconnect when separating the pcb from the outlets/box.
With the pcb in your hand, you will see the RANet Receiver
Detach and look underneath. One of the 6pin headers has a GND marking. That's the black wire of the programming cable you use to program RA.
Connect the programming cable to the RANet Receiver.
Go to Arduino and make sure to change the board to ReefAngel w/ optiboot
Load the code below to the RANet Receiver.

I just happen to have a pic of the RANet receiver. This is what you're looking for.

Put this is in setup()

Code: Select all

ReefAngel.AddRANet();

Thank you! Found it shortly after I asked, go figure.

[bencollinz]

another question about the expansion. I just go back in town after getting it setup. Last night I noticed that every 10-20 min my refugium light would turn off for a second then right back on. This light is hooked up to the wireless relay expansion. I think the expansion is losing connection to RANET, turning it off then back on. The box is only ~3 feet away from the controller. Is there any way to check/fix this problem?

I'm having this issue as well. My main lights keep flashing.

Did you try this?

Open the enclosure box
Remove all screws to free up the board inside.
You should be able to pry the board from the outlets.
Pay attention to the Logo LED lead wires. Make sure to disconnect when separating the pcb from the outlets/box.
With the pcb in your hand, you will see the RANet Receiver
Detach and look underneath. One of the 6pin headers has a GND marking. That's the black wire of the programming cable you use to program RA.
Connect the programming cable to the RANet Receiver.
Go to Arduino and make sure to change the board to ReefAngel w/ optiboot
Load the code below to the RANet Receiver.

I just did this. We'll see if it helps.
Here are some pictures for others in the future:
"You should be able to pry the board from the outlets."
I was a little disappointed to see that ALL of these black boxes were not pushed onto the board all the way

This still occurs. Just not as frequently.

Did you confirm that the box requires 10 seconds now to assume connection loss?

yes. 10 seconds.
