L203 not starting
I'm having a serious issue with my L203. After rebooting my system it doesn't boot anymore. The only thing I'm getting are a red power LED and 3 slow blinking green LED's for each of the controllers. No network connection, nothing else.
Tried refitting the SD-card, but that didn't fix anything.
Please help me fix this, as long as my unipi is out = no lights in the house.
RE: Stuck Relays
@tomas_hora I've checked it... the 2.01 and 2.02 worked for a while when I got the device and after about week of normal use (they are auto triggered a few times a day trough pimatic based on some rules) they didn't turn off all the time. I thought it was an error in my rules, or some problems with pimatic. But they are just "always on". I've even went so far as calling in a second opinion with a guy that knows more about electronics than me and he told me that it could be a fused relay.
What do you mean by a "different relay being switched"? When I trigger 2.01 the LED on the Neuron at 2.01 goes on, and off accordingly. Same for 2.02. I currently use half of the relays on my L203 so far.
I've been playing around with my Neuron and I must say, I'm quite happy with how this device works. Got my groudn floor hooked-up to it and doing some great stuff with it.
After some weird behavior, I've found out that 2 of the relays that I'm using are locked in a closed (always on) position. RO2.01 and RO2.02 have this problem, and are used to turn on a Raspberry Pi and an 24" LED screen. Both of the don't draw too much power, and are seperatly hooked up to the device (Pi on 2.01 and screen on 2.02).
The LEDs on the neuron still indicate ON/OFF when triggered, and I hear a faint clicking of the relays... but when I use my multimeter, it's quite clear that they don't work.
Is there a way to fix this without opening up my device and voiding my guarantee?
RE: Dead on arrival?
Hey @tomas_hora ,
This is the output that I got :
Board on /dev/spidev0.1 firmware=5.0 hardware=0.16 (B-1000-1) Board on /dev/spidev0.3 firmware=5.0 hardware=8.16 (E-16Di-1_U-14Ro-1) Board on /dev/spidev0.2 firmware=5.0 hardware=8.16 (E-16Di-1_U-14Ro-1) Board0 PTY0 /dev/pts/1 Starting loop
Dead on arrival?
I've been testing with my neuron L203 for a few days when I had some time, and it seems that after many attempt, the complete RUN2 section seems to be dead? I've played around with Mervis and Node-RED and I just can't seem to activate any of the relays on this part of the board.
The LED on RUN2 is blinking in a different way than RUN1 and RUN3. It skips every other blink and shows a slightly red LED instead. Didn't notice this odd blinking as I was so focused on staring to use this awesome device. Is there a way to check this on a lower level? I don't want to open the casing, as it would probably void my warranty.
Video of the blinking right here:
Hope to get a quick solution for this issue.
