I hope so too. I think I should point out that I’m a mechanical engineer by education. Electrical stuff is hard for me. So maybe double check stuff with a multimeter first.Thank you for you help. I hope nothing fries when I power up
Yes or you can use the power1 header for 5v gpio. These are straight from the pi and don’t use the uln2803.So then I would connect 5v to the 12v j5 since my relay is 5v.
Hopefully not. I contacted Michael Lane to see if he will be making anymore of his hats and have not received a response.I definitely bit off more then I could chew with this entire DIY tank/stand/light/controller/ custom control board! At times this felt more like a job than a hobby to enjoy. I muddled through one little step every week or two as I finished the last 10% of my massive DIY build.
So now over 2 years since I started my rebuild with a move in between I'm finally at a point where I can start getting my Reef-Pi up and running my tank! I got the raspberry up and running several weeks back didn't go any further until the other day I tried to get my power controller up and running. I forgot I left the relay power unplugged so I went ahead and plugged it in and everything turned off so I immediately unplugged the power. That shouldn't be happening cause all the relays are wired NC. A couple hours later I was thinking about it and realized the relays are 5v and I had 12v going to them! #honestyinreefing Also at some point while the power was on I was moving wires around for some reason and the DC ground hit the AC rail that goes to my relays! It made quite a pop!
On Sunday I installed the buck to reduce 12v to 5v for the relays but I didn't mess around with the raspberry until yesterday. IT WOULDN'T TURN ON! I'm pretty sure I fried the Pi. I ordered another today and hopefully I learned a lesson to turn off all power when in the controller. Also I really hope I didn't fry anything else like the ML hat ?
Ouch. Keep us posted.I definitely bit off more then I could chew with this entire DIY tank/stand/light/controller/ custom control board! At times this felt more like a job than a hobby to enjoy. I muddled through one little step every week or two as I finished the last 10% of my massive DIY build.

That is the route I will probably be going as well.I will be buying a robotank board if the hat is fried
Standard credentials for reef-Pi login set by @robsworld78 script is:The script worked. Reefpi is running. I was able to get to the log in screen but I can't log in! Says wrong credentials! @robsworld78 I used your script to install reef-pi but it appears my user name and password aren't correct?
Yeah as @Sral mentioned the name and password you choose during the install script is for the Pi, not reef-pi.The script worked. Reefpi is running. I was able to get to the log in screen but I can't log in! Says wrong credentials! @robsworld78 I used your script to install reef-pi but it appears my user name and password aren't correct?
Sorry that didn't go well, sounds like during the install script you selected the option for a Robo-Tank controller, that replaces the database and has all the connectors assigned for the controller. The ML board will be using different GPIO's so you'll need to change all the connectors that's why all the relays didn't work as expected.I had a h**l of a time getting my equipment relays to function properly. I don't know if it's the reef-pi programming or the robo-tank installation files or the ML hat or the fact that i shorted Line to the low voltage ground months back, but only 2 or 3 out of 16 of the GPIO addresses were correctly controlling the connected equipment. I found 3 GPIO that didn't work no matter what. I ended up reassigning port numbers until the intended equipment functioned when turning on or off in the equipment tab.
I now have the ATO and temperature controller up and running. Also set up timers for my fuge lights.
The Display light controller is another issue. Reef-pi won't recognize the pca9685 that is integrated into the ML hat. @robsworld78 @Ranjib @Michael Lane
