Reefpi error

Danghost22 · Dec 4, 2020

So I’ve been trying to setup a reefpi for a while now and whenever I would go to setup my PH probe it wouldn’t pickup anything and it gives me the error attached. What am I doing wrong? Also what is the other error

Well, I don't know the exact answer, but I can tell you two things. First, it looks like you have it configured to send you email alerts or similar, but the configuration for that is not correct (wrong user/password?). Second, there is an issue physically communicating with the ph probe from the raspberry pi

Thanks for tagging me in @eag ,
The email error is related to gmail authentication, you have to use application password , not email password there , details are discussed in adafruit guide 1 under telemetry/alert section,
For the ph circuit error, it looks like reef-pi is not able to talk to the device in i2c. What circuit you are using ? If you are using ezo circuit make sure you follow their documentation to convert it from uart to i2c mode (reef-pi docs does not mention this, I’m working to update it). Lastly make sure you are specifying the i2c address in decimal values.
Let us know the details if you want more help,

Okay so I just wanna update everyone on what I have done so far I have gone into the configs and added dtparam=ic2_arm_baudrate=10000 along with making sure I have these in the config (see attached picture) still nothing has worked

@Danghost22 can you answer the question i asked? what ph board you are using? if ezo did you change it from uart to i2c mode?

Sorry for taking so long to reply life got complicated. Okay so what I’m working with is the ezo and in terms of the uart I can’t remember fully but I will check. https://www.robo-tank.ca/Reef-pi-Deluxe-Aquarium-Controller-AC-Power-Bar-Fully-Assembled this is what I’m working with hopefully it provides more details
