It is more flexible than the ULN2803 many of the reef-pi were built with.

Actually, the PH value using the API seem to be continently .07 less than the dashboard - is this a known bug?

Not that I’m aware of. I can check the code, if it’s due to calibration

In my testing The readings command does return the proper array including last values of both current and historical- but something seems off with the read only, I was thinking missing cal offset too. Thanks.

overcurrent? curious, are you using 2x of required capacity of that mosfet?
OP

could be kickbacks? diods will help? I don't know.. I'm kinda guessing. I think you need some passives to protect the transistor
The mosfet that blew is in the driver that came with the light. Doubt that they over engineered it.

Has anyone tried "spoofing" a sensor and using a physical button/switch to trigger a macro?
Basically looking at making a push-button feed mode and a push-button or two some some equipment.

I have used the file driver to do something like that , for my model rail road setup.

How did you implement it?

I used a digital input using the INLETS Connector Pi17 pin - it under the ATO feature. I use it for a skimmer overflow sensor but this would work for a switch to trigger a MACRO I believe. You may need to hold it for 2 seconds or so but good to debounce anyway.

The check frequency on the sensor would have to be quite high, like 2-3 seconds to register the button press.
May have to play with it.

Yes. I have tried exactly that using the ATO function - No bueno / Werk nie lekker nie / Ai lunga gahle
I can get that configuration to trigger a Macro with only one step. As soon as the macro is more complex, it doesn't work. For example, if the macro just turns a system on or off, it works, but won't run a multi-step macro like my "Feed" one.
I've written a detailed post previously on my experiments with this - I'll try find it.
Would be really cool if this was possible.

Dang. That's a shame.

Yes, share it please. I can try debugging it.
Next release will have some timer improvements that should simplify things further

Hello, I have a little problem with 4.1 version, how can I change the colour in the dashboard graph? because the line is white on a white background.
I'm using Roberto Buti Ph board, two for ph probe and one for redox probe , sometimes I found a reading error. every 5 minutes I check the value, it's because i'm reading on i2c at the same time? or because the baud rate is too fast?

+1 I'd really like to have the same thing, too lazy to get phone out etc for feeding. I was thinking along the same lines with the ATO function like a switch, will have to see if there are any other alternatives that I can think of.
Is there any possibility of getting a interrupt based button functionality in reefpi? Maybe one that just writes into some variable that is then caught later by polling or something?
Catching button presses with polling is either really annoying to use or unnecessarily complicated hardware or cpu utilization wise.
Thought about doing a button/switch board too recently but it doesn't seem all to feasible currently

I would use file-analog input for this and a phyton script. Python to monitor the button an file analog to feed in to reef-pi. Actually you could use 2 input file so the next scheduled feed would be disabled for a certain amount of time.

Interesting idea, What about python to read the input and then use the API to run the macro? You can call the API from the same python script. See my post a few pages back from an example.
