Well guys I may have cooked my Pi. I was adding another 2 channels to control more outlets and my have shorted 12v to the output gpio pin and after a few attempts I was able to get the Pi to reboot and I had to reinstall Reef-pi to get it to load and now not I/O work at all. I have another Pi on the way tomorrow (Thanks Amazon Prime) I am just wanting to know if that was actually my issue and should i replace everything to be safe I have two PCA9685, also the parts to build another outlet controller and lighting controller.

Thank you
PS. I know I should have shut it down but the IP seems to change every time I do and I was being lazy and didnt want to look it up again

Access your pi using hostname.local instead of IP, that way you don’t have to remember the ip , and you won’t care if it changes or not

You have to test individual component to check if they are fine or not . Without those details it will be hard to recommend what to test

Ok. On with my lighting saga. I thought I had this figured out.

I got the Meanwell LDD700H driver connected up and the light works.

Next step is to configure the dimming....... Connected the "dim" pin on the driver to GPIO18 on the Pi.
Went to Configuration > Settings.
Enabled "Lighting"
Reboot for good measure
Went to Configuration > Connectors > Jacks and tried to declare a jack on GPIO18 using rpi as the driver

Here's where it goes south - I get the pink Box in the top right corner of the screen with "error failed to create : error invalid pin 18 http 500

Obviously I missed something basic again. Appreciate anyone putting me on the right path.

Gpio pin 18 is pin 0 in reef-pi , and gpio pin 19 is pin 1 . So use 0 in your case , since it’s gpio 18. This is something to do with Linux , I’ll explain later.
And sorry for the trouble , I thought I called this out in the guide

I created the jack on pin0 and I got the following error in the dreaded pink box LOL

{"error":"Failed to create. Error: open /sys/class/pwm/pwmchip0/export: no such file or directory"} | HTTP 500

It still created the jack, and I could use it to create a light, but dimming didn't work.

I did try change the Pi PWM frequency as Ranjib suggested a few posts up, but nothing.

Question about Adafruit IO. Can you have feeds from multiple devices on the same dashboard? Maybe a stupid question but I couldn't see a definite answer while browsing through the documentation on their website.

do you have pwm module enabled? you have to reboot once you enable pwm module. https://learn.adafruit.com/reef-pi-installation-and-configuration/raspberry-pi-configuration

Yes. A feed is associated with a single data source, such as an individual pH sensor, water level sensor, temperature etc, hence they'll always be associated with one originating Pi. A dashboard can be composed from many feeds that belong to a single or multiple Pis. But remember the free account has a limit of 10 feed i think.

That's awesome. I just found my way around the fact that Reef-Pi don't support humidity monitoring yet. I'll just set up an arduino or Pi0 with a sensor that'll send a feed to Adafruit IO. That way I can still monitor everything and see correlations between different data streams. Might not be able to have Reef-Pi react to humidity input but for now I don't feel the need to. :)

Confused.....


Have been logging into reef-pi for weeks. Password was saved by windows and used this to login.


Today it says my login credentials are incorrect..... and I never changed the password.


Please advise how I may access reef-pi without starting over :(

Did you made any changes in credential section earlier, and not reloaded? double check your username and password, they are case sensitive. Does it work if you access them in private/incognito mode from your browser

Sorry for my ignorance I have no idea how to do that. Also my new Pi arrived today and confirmed I cooked the old one so moving on with the new one everything is back working and I will be ordering a spare and keep it loaded with a copy of the SD card ready to go.

So if I changed my hostname from raspberrypi to lightspi that means I can ssh into by lightspi.local, won't matter if ip address changes?
One more thing, the ip address in reef-pi is how I access on mobile, can that change or is it always kept the same?

Yes, spot on. Reboot your pi after you rename it

Whatever is applicable on laptop the same is true for mobile as well. You can access reef-pi as lightspi.local on mobile as well, as long as you are connected to home WiFi
