Robo-Tank v5.10 is Ready

[Rob F]

Hi, I have an update ready to go. This one includes some fixes and calibration is back for the Atlas circuits and new Robo-Tank pH circuit. This update you should get an email with the password for the download. With this update you will get a splash screen on the display prompting you about the update, make sure you upload the controller sketch before pressing OK on display.

Here's a list of what was done.

Additions

• Added option to select Robo-Tank or Atlas probe circuit
  
• Added auto calibration feature for Robo-Tank and Atlas circuits
  
• Added probe health report for Robo-Tank probe circuits, shows slope, offset and calibration duration (not compatible with Atlas circuits)
  

Improvements

• Changed pH view to 1000ths
  
• Stop logging min/max values when calibrating probes
  
• Adjusted the float switch triggering points for custom rules and alerts 
  
• Removed less than / greater than option on alerts for float switches, if that was changed it could have effected alert
  
• disabled custom rules for temperature sensors while calibrating
  
• disabled custom rules for flow meters while calibrating
  
• disabled custom rules for probes while calibrating
  
• disabled alerts for temperature sensors while calibrating
  
• disabled alerts for flow meters while calibrating
  
• disabled alerts for probes while calibrating
  

Fixes

• Combination on/off schedules with no repeats wouldn't resume to correct state when controller was restarted
  
• When Celsius was added to custom rules it affected rules that weren't based on temperature
  
• CO2 wasn't calculating correctly if kH view was PPM or mg/L
  

When you select a probe to calibrate you get the following screen. Here you choose either a single or dual point calibration. You can also view the slope, offset and calibration duration for the last calibration, this isn't available for Atlas circuits only works with Robo-Tank circuits.



When you select the calibration type you get the page below, the instructions and title change based on type and point. As soon as you press the "start" button you get a confirmation prompt and if accepted all previous calibration data will be lost.



Once you start calibration you get the page below. It'll stay here until the box is full of yellow bars or if 10 minutes comes first. What this does is record the pH value and every 3 seconds it compares the current pH to the value it recorded. If the current is +/- more than 0.003 it will record the pH again and continue to compare. In order for the auto calibration to continue the pH must remain within +/- 0.003 for 60 seconds to be considered stable. Using the Robo-Tank circuit this is easily achieved however using the Atlas circuit it's a little hard that's why I added the 10 minute time out. Using my Atlas circuit its common for the pH to jump more than +/- 0.003 so you might have to wait until it times out. My Atlas circuit isn't isolated so I'm wondering if that's why it jumps a little bit compared to my circuit, maybe someone with an isolated Atlas circuit can confirm it's more stable.

Once this finishes it will go back to the screen above for the 2nd point if selected otherwise you will get the next image.



When calibration is finished you get the following page, this shows the offset for point 1 which is important. This should be within +/- 30mv, typically this means the probe needs cleaning. You also get the slope for your probe which should be between 85% - 105%.

The duration is the total time you sat on the screen above minus 60 seconds for each point as it was considered stable at that time. Currently this has no weight in the overall probe health as results can be all over the board in my testing.



The page below is simply instructions on cleaning your probe, cleaning it will increase the life span of the electrode. You get to this page by pressing "press for more info" on the 2nd image above.
