Its not steady. its varying.. but the old values is making the chart y axis so large that the new calibrated values are not being visualized correctly. Bare with me, I'll list down the steps to use reef-pi db command to get rid of the old values,
- Stop reef-pi (sudo systemctl stop reef-pi.service)
- Use reef-pi db command to list the ph probes (sudo reef-pi db list phprobes). Obtain the probe id from here. For me it shows something like this
Code:
{
"1": {
"id": "1",
"name": "TestPH",
"enable": true,
"period": 2,
"analog_input": "1",
"control": false,
"notify": {
"enable": false,
"min": 0,
"max": 0
},
"upper_eq": "",
"downer_eq": "",
"min": 0,
"max": 0,
"hysteresis": 0,
"is_macro": false
}
}
- Notice my phprobe id is 1. Next use this id to obtain the ph readings values
Code:
sudo reef-pi db show ph_readings 1 > readings.json
. This should dump the readings in readings.json file, edit to and remove all the bogus values (you'll see values in the range of 1000s (way outside 0-14), delete those.
- The reupload the file like this:
Code:
cat readings.json | sudo reef-pi db update ph_readings 1
- Start reef-pi again (sudo systemctl start reef-pi.service)
Thats it. your old data is gone now.. and the graph should automatically reset and show you the new values which should be in 5.5-10 range at worst, but with daily cycle.
For ease of editing i pass the reef-pi db output via jq command, it indents the json file , making it easy to read/edit.
To install jq command
Then to use it execute the 3rd step like this:
Code:
sudo reef-pi db show ph_readings 1 | jq . | readings.json
Sorry for your trouble. Let me know if you try this and if it worked. Happy to helo you through this...
You can remove the solder pads but not the resistors. The resistors are always connected directly to pins on pca9685 via the pads. The solder pads let 5v through and pull up the line changing the address. So the bottom traces going to solder pads from pca9685 would need to be re-routed to the resistors and then add 5v to whatever lines you want to change the address, the many combinations is why it has so many addresses.
add ph and when feeds are shown add leds again to reefpi? Thats lot of work..
