I've never used it and yep that is a pretty penny but if all indicators are that it works well AND you feel it will make you happy then pull the trigger! :)
I do use a wifi PID but it is a much more complex one than the Auber wifi PID. I can tell you that you may also need to look into a so called wifi "extender". You can get one on
Amazon costing anywhere from $20-$75 that should fit the bill.
My smoker is juuuuuuuust in range of my wifi signal and most of the time I have no issues with it getting signal without using an extender. The signal strength reported from my wifi PID is around 40% and when it falls to 37% that is when I get intermittent connection issues. As long as I am 40% or higher I am golden.
Why does it matter so much?
When you set your temperature alarms/alerts your unit needs to be able to connect to your homes wifi in order for it to notify you on your phone when the alarm/alert temp limits are hit.
This is HUGE when you run into situations where an
AMNPS pellet flame flare up occurs causing major heat increase AND burning up all your pellets in minutes if you don't catch it!
OR when the ol' lady decides to blow dry her hair in the other room and trips the breaker your electric smoker is on and instead of going and turning the breaker back on she just goes to another room to blow dry her hair lol
OR when any other situation occurs that causes the smoker temp to drop too low or raise too high.
Finally, it is also nice to be able to smoke a brisket or a pork butt overnight and just go to bed knowing the meat temp alarm will wake you up at like 7am-8am,etc. when you hit the temp to alert you to check the meat for tenderness/readiness :)
Anyhow I just wanted to add some advice and some of my experiences with a wifi PID so you are as educated as you can be. I hope this info helps! :)
