reef-pi has suddenly stopped recording ph data (Robotank)

[kdx7214]

I've been running reef-pi on a RoboTank for quite some time now and it's always worked perfectly. Last both the pH and one of 3 temperature probes stopped recording data. I've downloaded and run @robsworld78 g++ script and it reads the sensor quite well and shows values in the range I would expect. The temperature probe probably failed and I've ordered new ones (that Rob recommended) but I had 2 extras so no worries.

I just can't seem to figure out why ph data would stop recording and showing up on the dashboard. Any ideas of what to check?

can’t say I have experience with your specific problem, but have you tried turning it off and on again ?
I would try the following order:
- reload ReefPi
- reboot the Pi
- disable the pH entry in the pH tab, reload ReefPi and re-enable the pH
- delete the pH sensor in the pH tab and create a new one
- delete both the ph entry in the pH tab and driver, reload ReefPi and create them anew

Afterwards you‘ll also need to reset the dashboard graphic to the new sensor.

Oops, I forgot to mention that. I've done a reload, reboot, and power off/on cycle and still no go. Not sure but it might be a data corruption or something.

you can try this

reef pi reset database

Can I wipe the data history from my reef pi - currently just set up on a breadboard for testing with temp sesors and timers. I'd like to wipe the cached historic data so that the dashbaord resets and only shows new data, how can I do this? thanks

Somehow it randomly started working again without anything else on my part. I wish I knew why it did it, but I'll count it a win

When it stopped working, please check the logs for details. If there’s an error, you should see that in log(as well as Ui). If it’s disabled or other not reading probes for some other reason, that too will be clear from the log.

Sorry about this, but it randomly started working again. I'm not even sure where the log files are for it. Are they accessible from the website interface?
