Temperature is the most important factor when cooking grills. But I think you know already or you would not be searching for pellet grill controllers. As these controllers help you to keep the heat to an optimal level, grilling will feel a lot easier now than ever.

PID controllers (Proportional Integral Derivative) are also known as pellet grill controllers. These devices are used to control the temperature, airflow, fan speed, and other variable factors in your grill. They utilize advanced algorithms to aid you when grilling. Moreover, they also show the current temperature and allow you to control it whenever you see fit.

If you are confused that which one should you get, don’t worry! I in this post, I’ll be covering not only things should know but also some of the best pellet grill controllers.

How Does A PID Temperature Controller Work?

As the term ‘PID’ means proportional integral derivative, its working mechanic is also quite advanced. Basically, this device handles proportional control through additional integral and derivative adjustment. Although the algorithm could be a bit complex, allow me to explain it in layman’s terms.

The purpose of these temperature controllers is to keep the environment to a set point. That means when grilling, it will try to keep up with the system with the temperature you set. It does so by controlling variables like airflow, temperature, pressure, and other factors.

The proportional part tries to correct the course according to the set target. Although the target value would never match because as the difference approached zero so does the applied correction. The integral part tries to cover the error that culminated from the proportion tuning. The derivative function slows does the correction as they approach the target.

What to Consider Before Buying the Best Pellet Grill PID Controller?


There is no one-size-fits-all when it comes to temperature controllers. Different brands come with different designs and requirements. That is why these pellet grills controllers too, come with different mounting options, probe, range and etc.

Due to this difference, the compatibility issue rises. For these reasons, it is the most important factor that you thoroughly check if the controller is compatible with your pellet grill smoker model. Because sometimes, they only fit specific models under the same brand. 

Number of Probes

The probe is the hardware that senses heat and conveys the information to the processing unit. Then the processing unit turns that heat into a number for you to see. Probes with made with material that can facilitate the flow of heat.

The wood pellet grills will have at least one probe. It is not unusual to have 2 or 3 probes. The more probes there are, the better estimation you will get. So, if you have the option to pick a controller with multi-probes, go with that one.


These pellet grills come with a range of displays. Among them, LED displays are the best. They light up brightly, and you can easily read them even outside under the sun.

Also, make sure the display is big enough so that you can read it from distance. It will be helpful when you won’t be at the helm and busy doing other chores at the distance. Being able to keep an eye on the temperature can be life-saving.

Temperature Range

Although most temperature controllers on the market cover the whole spectrum, sadly not all. The wood pellets can burn from 150 degrees Fahrenheit to 550 degrees Fahrenheit. So, make sure the device can work within this range.

A little slip to any side and you will be wondering why the grill does not taste so good. Even though you maintained temperature as per the instruction.


Pellet grill controllers come in various shapes and sizes. You will find it from bulky ones to small ones. It depends on your setup. If you like to camp a lot you should get one portable and lightweight. But you will be sacrificing extra features. On the other hand, bigger pellet grills come with more features, and most of the time they tend to be very durable.

Wireless Connection

The wireless connection could be a life-saving feature on pellet grills controller. Imagine you are gossiping with a guest or doing something so that you cannot be near the grill. But, with this feature, you can still raise, have lower temperatures or turn it off completely. This is a feature that once you taste it, you cannot live without. If your controller comes with a wireless connection, all of a sudden you will have extra time to distance yourself from the grill.

Additional Indicators

Controller for Pellet grills also come with many additional indicators. Although they vary from model to model. Some indicators are a smoke setting indicator, ignition indicator, fuel rate indicator, low and over-temperature indicator, more or less smoke detector, and many more. If you see you could make good use of some of these. Then, you should go after such models.

How I Picked The Best PID Controller

Making the list with the best pellet grills controllers was no easy task. You will see hundreds of results once you search google or amazon. So, how did I choose?

I had to look through the top pellet grills and made an initial list considering quality and features. Still, it was not enough. Then I went through the user review. From those hands-on experiences, I got to know the inner intricacies, good and bad sides of these controllers. 

As everyone has different tastes, I chose to categorize these controllers of pellet grills to fit everyone’s requirements. For example, if you want something easy to use or portable, I got you covered. There are also different categories, that I’ll be explaining in the review section.

Just in case if you’re in a hurry….

Check these two best models from my review unit. You won’t regret it later.

Does the Grill Pellet Controller Really Help to Make Taste Better?

Yes, it does if you use it properly. Let me explain how it does so.

best pellet grill controllers image

If you are experienced in the craft of cooking grill you should already know the temperature is the most important factor. In case you are someone who just starting out, always bear it in mind.

It takes great cooks years to master the temperature. For ordinary folks who grill from time to time, it would take a lot of trial and error to find the sweet spot.

This is where the pellet controllers come in to help. First of all, it shows you the temperature. So, you are always informed how much heat is there.

It also lets you ensure temperature control. This way you won’t have to go through the lengthy process of trial and error. Just pick up the recipe cook, and set it to the recommended temperature. As you will be mastering the heat settings quickly, the taste of the pellet smoker will keep improving at a proportional rate.

Manual Checking Vs Pellet Controllers

The whole idea of manually checking heat would give you an estimate. For example, the common practice is to put your hand five inches above the grill. Then count how many seconds you can comfortably keep your hand on place with current smoke pellet smoker temperature sensor.

If it is 5-6 seconds the heat is around 250 degrees, if it is 3-4 seconds the heat is around 350 degrees, and so on. It is not inaccurate but also dangerous. You could get burned if anything unexpected happens.

On the other hand, pellet grill smoker controllers are not only very safe but also accurate. On top of that, it ensures precise temperature control. No matter how sensitive your hands are, this device can beat manual checking any day.
