On the app it is marked with an A at the bottom. You are correct in that auto function does self regulate. However there have been instances where fans randomly turn off then back on, same with lights. And this is only happening using auto not advanced automations.
Use this:
Not this:
You will the see advanced on your main screen instead of auto. Just trying to possibly save some headache down the road. They could have fixed that problem with the updates but I’m not taking that risk.
Bracketh explained it much better than i did 
I dont have my lights hooked up to the app. I use a seperate timer for them. The thing with the Advanced mode is everything runs off a timer. I would have to restart my fans all over again in Advanced automations… they turn off in Advanced
Its just my fans no lights… it looks like Advanced mode is just for lights
Advanced mode is for everything. Lights, fans, exhaust, Humidifier, it allows full settings for everything. It also makes it easier to switch from early veg- late flower without changing each individual item.
This is way over my head…i am confused. I guess i will just have to start experimenting.
Start up here on this same thread. About post 101 and work your way down it might help explain some. If you still need help let me know.
Hola!
I just got a couple 69pros and various uis gadgets.
I use a AC Infinity Raxial inline fan in my tents inputs to pump cooler, drier air into my tents from my lung room.
I know I can control the Raxial on off by way of the uis plug outlet.
Can i create two automations like this:
Heat & Cooling
Devices:
heater on a outlet
Raxial on an outlet as cooling.
Having the Raxial start when air needs cooling.
Second automation:
Humidifier & dehumidifier
Devices:
AC Infinity humidifier (t3 or t7)
Same Raxial on same outlet as above.
Having raxial start when air needs to be drier.
Is this possible? Or a conflict?
It’s possible, as long as the automation times and devices don’t conflict. The Raxial would need to be on its own automation, if I understand your situation correctly.
And that automation for the Raxial would need to have triggers for both heat and humidity.
Right back at you! 
Sorry so late, @Newt has it covered. Create a seperate automation for each device and ensure the parameters pass the smell test and dont conflict.
I still have the old controller, so have been watching from the sidelines, but I have a question.
Can you set a variable speed for the OFF setting on the exhaust fan yet, so that it never really shuts off, but just slows down to a slower preset?
You should be able to.
So for OFF set it to 1, then ON set your max, then in AUTO set your trigger to ramp up(ex. 75°). In settings make sure you have transition set to 1° so it only ramps up by 1 speed for every 1°.
And that should have you covered
Why does the VPD calculator have a different reading than the pro 69 controllers sensor probe reading?

@MartyMarajuanaseed Look at the leaf offset. On the chart from vpdchart.co it has a -2ish leaf off set temp. To get the same readings on the chart that show on your controller you would have to plug in a +3° leaf temp difference into the chart. So I’m guessing on your controller you have a +3° leaf offset temp. You can unlock to adjust the leaf temp here:
I see, so i add 3% to the leaf temp offset…i am not sure how the math works but i appreciate the information. I will just remember to add the 3% to the leaf temp setting. Thanks. I am starting my 3rd week of flower today and i am trying to get everything set so i dont end up with crispy molding buds!
I know ive got to get the RH down to at least 55% and its way to hot at 87 degrees… i need to make some changes real soon…
It’s not so much about adding or subtracting a degree to make your numbers fit. It’s intended for you to input your air temperature, which is 86°. You then need to take a reading of your leaf tempature using an IR gun and input that into the chart.
For your controller, you just go into the settings and adjust your leaf temp offset to the difference between air and leaf tempature.
So ideally, you would be in the range of -2° to -3° leaf off set.
Yes, i ran over and checked the VPD leaf offset setting and its on 3°. I think i read that thats where to set it at…
I have the door of my tent open about a foot to let some cool air in. Its 88° in there right now!
What is your actual leaf temperature?
I have no clue… how do you test it?
