Haha! I didn't catch the irony of that error message earlier! Nonetheless, I still have not figured this out, which means my graphs can't be reset and I can't really tell the regularity and the length of time the pump is running at a glance...
Man!! I'm so dismayed. I was going through the manual, put all my credentials in, hit update. Then reboot and my pi froze, turned off and never turned back on. I just have the red power led come in. Nothing with the activity light. I tried 3 different ad cards, different power cords. I read about the polyfuse, so I'll let it sit for a few days, but man that sucked!
Is there any chance you could elaborate on how you are pulling the switch to ground? I have a different feeder I want to use but I need to figure out how to bypass the manual feed button by pulling it to ground via reef-pi.My Eheim went for a swim recently so I popped it open after doing a full wash and dry cycle. Still works.
You’ll want to signal the K1 or K2 buttons, in the picture orientation left to right. The edge of the board is battery ground and the inner button contact should be brought to ground to activate.
Thank you, I'll definitely take a look at getting a transistor, unfortunately my pi went down after trying to reboot. I cant get any activity out of it and I've tried 3 different sd cards, all of which I know to work. Kinda at a loss on what happened to it

Nice IC, if I had known the PCA9507 before I would have used it instead of my current solution.
Thank you for your answer, I'll try LTC4311 and shielded cableNice IC, if I had known the PCA9507 before I would have used it instead of my current solution.
I'm using an Adafruit ISO1540 to isolate my Pi's 3.3V against the I2C's 5V. Currently that's slightly stupid, because both are fed by the same 5V DC/DC converter
Afterwards I hook up my SDA/SCL lines to a USB socket and latch an Adafruit LTC4311 I2C extender onto it. It basically does what your PCA9507 does a swell, it is a dynamic pull-up which shorts the lines to VCC, exactly what the PCA9507 has on the A-side. Everything is connected using header pins and header cables, as you can see in my build thread.
So the PCA9507 should be fine, if you have a good connection and cables. Personally I'm using shielded USB-A cables. Not the cheapest option, but it seems to work. I can get a seemingly stable I2C connection to my SCD30 over 1m distance.
I would suggest to check shielded cables, like a Ethernet cable and to try placing the PCA9507's A-side onto the side of the cable leading to the sensor.
Maybe start a new thread and if possible post some pictures of the internals and we can maybe point out some things to test it. I can explain how to pull it to ground but we need to figure out how the feeder works and where you would make the connections.
Wow I can't believe that's priced how it should be. Based on the ruler my guess is it's analog, unfortunately the Pi doesn't have any analog pins so if you wanted to know the actual water level you would need to add a ADS1015 ADC to your system, reef-pi has a driver for it. Of course you would need to figure out the wiring, if someone hasn't done it before on a forum it could be difficult getting it right. If you were successful you would get an analog value from the ADS1015 which you would use as a reference. If it is analog you could still connect it to a digital pin on the Pi and it would either read on or off but anyone's guess as to where that might be on the ruler.
I noticed these Neptune liquid level sensors have a familiar connector. How difficult would they be to add to reef-pi ATO?

As @robsworld78 mentioned it’s not straight forward if you don’t know the internals. E.G. what contact is ground, VCC and data lines. Next, what kind of data is used, e.g. is it a digital interface like I2C or SPI, is it semi-digital giving a PWM signal or an analog voltage.

This is awesome . You plan to opensource the design ? I’d love to build one
We should be able to integrate these things using the Esp32 driver right ?Wow I can't believe that's priced how it should be.

ADS1015 12-Bit ADC - 4 Channel with Programmable Gain Amplifier
For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1015 provides 12-bit precision at 3300 samples/second over I2C. The chip can be ...
Chances are you can hook them up with Esp32 and use ph module (analog input ) for monitoring and control

Yeah I was thinking analog... one of the things I noticed was when users pair to Apex they have to specify the size of the LLS they are adding, I feel like if it were I2C, etc, the size would be built in and it would just send across the measured depth - I also feel like the top would be a little bulkier since I assume it would need to have a circuit built in.
I'm concerned about that too - I guess it's possible there's contacts to maintain compatibility with other Apex Fluid Monitoring Module devices.
Awesome. I think I'll buy one to see if I can figure out what's going across the jack. Hopefully buzzing it out with a multimeter is adequate to get started.
It's highly unlikely it would be I2C or SPI, neither of those would ever be used like that in a true commercial product. I think Apex uses CAN bus for all their extensions but it's unlikely the sensor would be that especially based on the price of this sensor.
Ah yes, I forgot you were adding the ESP32, that will definitely increase the number of sensors that can be used.
