Auber 1520H setup – auto-tuning on Model #2 – Auber smartphone app

I got my Model #2 on August 13 and did my first cook August 16 after assembling the cart and arranging things on my covered patio so the smoker cord would reach my outdoor GFI outlet. Over the course of several more cooks after that, during which I monitored both meat and cabinet temperatures with my Thermoworks Smoke, I decided I wanted an Auber PID to avoid the rather large temperature swings inherent in the #2's analog control system.

My Auber AW-1520-H arrived last week, and I got it set up last weekend. The wifi connection was a problem at first because my Netgear router automatically assigns a frequency based on the signal strength available at a device's location, and my #2 is only about 25-30 feet from the router, so the Auber wasn't getting wifi connection on the 2.4 GHz channel. I solved that problem by setting up a guest network on the router that only works on the 2.4 GHz channel and connecting the Auber to that network.

Even with the stock Bradley PID settings, the Auber held the smoker within 10̊ to 15̊ of the set temperature during a cook this past Monday.

Late this afternoon I got around to doing an auto-tune. The smoker temperature probe was clipped on the next-to-highest rack level several inches away from a standard metal loaf pan filled with damp sand. The #2 analog control has not been bypassed and was set at maximum. Auto-tuning began at 4:30 p.m. and ended about 8 p.m. The average ambient outdoor temperature during that time was 65̊. I used the recommended program: (1) 140̊ for 30 minutes, (2) 225̊ for 2 hours, and (3) 140̊ for 1 hour. Results were:

P – 80
I – 886
D – 221

I will update this post when I have time to do another cook using the Auber – probably early next week – with information about how well the Auber manages cabinet temperature with these PID settings.

Comment on the Auber smartphone app: I saw some older posts criticizing the Auber app. I found that the current Auber app for Android phones is intuitive and very easy to use. It enabled me to set up the auto-tune session very quickly. I plan to use it to set up all my smoking projects going forward. I can't speak to the iPhone version, but I assume it is equally good.

Well, apparently I did everything right when I did the auto-tune. I did a 3-hour smoke of a tri-tip today, and the Auber held the cabinet temperature within 1 degree of the 250 degree set point -- most of time exactly on 250 degrees. This is without a permanently mounted probe 1 for the Auber -- I had probe 1 mounted in the middle of a rack on the highest rack level, with the tri-tip centered on a rack two rack levels below that.

I'll probably get around to permanently mounting an Auber probe 1 and bypassing the SI #2's analog control when it warms up next spring.

Question for those who have permanently mounted probe 1: Where did you get the spacer?
 
I also have an analog #2 that I upgraded with an Auber controller. I got my controller off of ebay (used) and the model I got works fine but because it is older, the wall mounted probe has been discontinued. I ended up buying another "food" probe from Auber (the curved one) and mounted that as my wall probe. I mention all this because while I don't know what your probe looks like, perhaps my mounting method could be of use to you or someone else.

What I did for the spacer - I bought an assortment of nylon bolts & nuts off of Amazon. I chucked one of the longer ones into my mini-lathe and drilled a center hole of the appropriate diameter all the way through the bolt. Then I mounted the bolt through the wall of the smoker and double-nutted on the inside. The probe slips through this and is basically held in place in the back by all the layers of insulation. FWIW I also got an assortment of rubber grommets at the auto parts store to protect the wire from the sharp edges of the back hole. I realize not everybody has a tiny lathe but perhaps one could use a drill press or something.

Hopefully these pics show up:
