If you’re a total gadget guy like me, then everything needs to connect to your smartphone. It just feels wrong to buy a new piece of technology and have it NOT connect to your phone.

While you can easily install a smart thermostat like the nest to control the temperature in your home, unfortunately the technology in bbq thermometers hasn’t quite caught up yet.

You face a tough decision between buying an older radio style thermometer (like the Maverick ET733) or going for a Bluetooth connected one (like the iDevice iGrill2).

While both styles will give you the benefits of wireless, so far only bluetooth can connect to your smartphone.

Bluetooth thermometers aren’t without their issues though. Range and connectivity can be a huge problem. Luckily for you we’ve compiled a list of the best available options and all the pros and cons.

So read on to learn everything you need to know before you rush out and buy a new thermometer,

iGrill2 Bluetooth bbq thermometerThe Best Bluetooth BBQ Thermometer  – iDevices  iGrill2 Bluetooth Thermometer

By far the best option if you want to connect your thermometer to your smartphone or tablet. iDevices have definitely learnt from their experience with the iGrill 1. They’ve completely rebuilt the app from the ground up, with much better bluetooth connectivity.
iDevices recently sold it’s iGrill brand to Weber. While the Weber brand is almost untouchable in barbecue circles, it’s still up in the air how well they’ll succeed in their foray into tech.
What we liked:
  • The increased Bluetooth range and improved pairing (should connect to your device in under 2 seconds) removes a lot of the frustration you experience with other bluetooth thermometers. While the 150 ft advertised range is still much less than the 300 ft range you get with the Maverick ET-733, it’s now enough that you can actually go about your business without worrying about loosing connection.
  • Having the ability to use 4 probes with a single unit is great. Easily monitor multiple smokers and / or multiple pieces of meat. Gives you a lot of flexibility for one thermometer. You only get 2 probes, but can easily order more off Amazon.
  • Rubber base on the unit has a magnet so it can snap on to your grill surface


iGrill 2 bluetooth thermometer appOne of the coolest features in the app, is the ability to name the different probes. So instead of trying to remember which probe is in the meat and which is in the grill, you can give each a custom name so that when you glance at your tablet or phone you can instantly see the temperature.

The iGrill 2 has a proximity sensor, so when you walk away with your device, it automatically shuts off the display on the base unit. This helps save the battery life when you are using your own device. When you walk back it turns back on.

If you put your phone or tablet to sleep, then the bluetooth connection drops, so you can’t monitor the temperature any more. Not ideal if you’re smoking over night.

While the range seems to be much better for most people, we’ve still heard of people having issues. Our advice would be don’t expect great results if you plan on spending time down in the man cave. If there’s going to be a lot of walls / certain types of material between your phone and the unit, you are going to have issues.

Watch this video to see the iGrill 2 in action. At the 5:02 mark you can see a good demo of how the bluetooth pairing works.

So far we’ve focused on the bluetooth and app, but how does the iGrill 2 perform? It’s capable of measuring between -22°F to 572°F. When tested in boiling water the probes are within 1 degree so it gets the tick for accuracy.

The 48″ probes are a nice feature compared to most other thermometers 36″ probes. The extra length gives you a bit more flexibility for how you setup your pit.

To use the iGrill you’ll need to download the Idevices Connected app form the App Store or Google Play Store.
  • iPhone 4s and up
  • iPod touch 5th gen and up
  • iPad mini series
  • iPad 3rd gen and up
  • Most Bluetooth Smart Ready Android devices


The iGrill 2 gets the nod for best tech thermometer. If you will get a kick out of seeing temperature graphs on your phone, and want the convenience of monitoring you’re cook from a single device then the iGrill is the best option on the market today.

If you’re not that interested in the technology, then because of the limitations of bluetooth then we would recommend just going for the Maverick ET-733 and enjoying the more reliable wireless thermometer.

Maverick ET-735 bluetooth thermometerRunner up bluetooth thermometer – Maverick ET-735 Bluetooth Digital Thermometer

 There’s no doubt that Maverick know how to make digital thermometers. The ET-733 and before that the ET-732 are the most popular mid priced digital thermometer on the market.

But how well has Maverick done at creating with their bluetooth thermometer and app? Unfortunately their foray into the world of tech gadgets has been a mixed result. So far.As a thermometer the ET-735 ticks all the boxes. Like the iGrill 2 you have the ability to connect up to 4 probes (the unit comes with 2). Each probe is 36 inches long which is enough to give you plenty of flexibility when it comes to setting up your smoking area.

The specs claim 160 feet of wireless range which is 10 more than the iGrill 2, but like that thermometer the actual range you’ll get varies a lot depending on factors like what type of material is between the thermometer unit and your device.

It’s a shame manufacturers feel the need to display the range in terms of open air, direct line of sight. The whole point of buying a bluetooth thermometer is so you can wander around the house (or take a nap), and easily check the temperature by reaching into your pocket.

Speaking of reaching into your pocket, how well does the app perform?
In terms of functionality, the ET-735 app offers similar features to the iGrill.
  • You can choose from default temperatures or customise them to your liking.
  • The app provides notification when target temperature is reached.
  • There’s a handy feature that lets you check the battery level in the transmitter

You’re experience with the BBQ Redi-Chek app is what makes or breaks this thermometer


When you talk to owners of the ET-735 they either love it or hate it. Initially the app was pretty poorly received with lots of issues with connectivity and very low range.

But like most tech products you get the advantage of regular updates and upgrades from the manufacturer. There was a new version released in October 2016 that seems to have fixed a lot of the issues with the app.

iGrill mini bluetooth budget thermometerBest budget bluetooth option – iDevices IGrill Mini

The iGrill mini is a great option if you love the idea of checking your smoker temperature from your phone, but don’t want to splash out for an expensive piece of tech that might not work in your house due to building material.

While it looks similar to the iGrill 2 reviewed above, it’s really more of a little sibling. Some of the key differences are:

  • Only comes with 1 meat probe, and you can only connect 1 probe at a time so forget about monitoring your ambient and meat temperature at the same time.
  • Gets about 150 hours of continuous power vs 200 hours on the iGrill2

Otherwise the range and the app is the same. Since it’s a fraction of the cost the iGrill mini is a solid option if you already have other temperature probes you can use to monitor the Ambient temperature.

If you want to start geeking out and graphing your temperature on your phone then god speed, just don’t expect it to impress those old school pit masters.

Wifi vs bluetooth bbq thermometers explained

Wifi thermometers have been around for ever, and while units keep getting better the technology isn’t very exciting. In the last couple of years we’ve seen an explosion in bluetooth enabled thermometers.

Still offering wireless connectivity, with bluetooth thermometers you can pair them with your smartphone or tablet.

So instead of carrying around a bulky receiver you can check your pit or meat temperature on your phone. These apps also come with some other cool features like temperature graphs, probe naming and custom temperature alerts.


Advantages of using a bluetooth thermometer  

  • Obviously having the app installed on your phone is the main advantage.
  • The phone app that you install gets better with every new release from the company. While the original iGrill app had issues, they rebuilt it for the iGrill 2 and made it much better. Now with each new release issues are ironed out, where as with and old thermometer if you don’t like how something works it’s impossible to change.


Sounds awesome doesn’t it?

In theory connecting your grill thermometer to your smartphone would be a huge upgrade. But before throw your old wifi thermometer in the dump, it’s worth looking at how well bluetooth compares.


Bluetooth was intended to be low power so the signal doesn’t propagate nearly as well as WiFi


The number one issue we have with bluetooth connected thermometers is that what you gain in new features and ease of use, you give up in range.


Common issues with bluetooth 

Compared to bluetooth, wifi thermometers are pretty easy to review. While range varies a little depending on the building materials of individuals homes, everything is generally similar.

With bluetooth on the other hand, the device someone is using (e.g. Android or iPhone), the version they are running, the location they are in, the version of the app they are running all influence the quality of the experience.

This explains why you see so many mixed reviews for devices like the iGrill 2. Someone using it on their iPhone 7 might experience flawless connectivity, while those running an older Samsung Galaxy struggle.


If you do decide to go with a bluetooth thermometer, here are some of the common issues you may 

  • Bluetooth antenna are notoriously lousy in certain types of phones. We’v heard of people get much worse range with the Samsung Galaxy compared to similar phones from HTC, LG and IPhones
  • Once you’ve paired your device, the app has to be running for it to stay connected. This can be annoying if you do long cooks and it will likely drain the battery life
  • It’s hard to know exactly what range you will get. While the iGrill 2 claims up to 150 feet of range, this can drop way down to 10 feet depending on a range of factors.
  • You can lose connection to your phone through the walls of the house. .
Deciding to go with bluetooth is all about tradeoffs. Having the temperature of your meat or pit on your phone is great, but it will drain the phone battery quickly.
If you do long cooks and like to take naps, you probably rely on the alarm on the thermometer to wake you up. With bluetooth you’ll need to make sure your phone is running constantly, and it’s plugged in otherwise your screen will shut off and you won’t get any notifications.
With an old reliable Maverick ET-733 you don’t have to worry about it turning off, or the walls of your house cutting off your temperature readings.

How to fix connection issues with your bluetooth thermometer

Bluetooth is still a relatively unreliable technology. When it works it’s fantastic, but we sometimes devices don’t like to play nice.

Since bluetooth is on the same frequency as 2.4 WIFI,  having too many devices can cause issues. Fix this problem by making your kids turn their phones onto airport mode…

OK when that doesn’t work you can try following these tips from the experts.

Goldtouch.com, How to Stop Bluetooth Interference From Messing With Your Other Devices

  1. Remove All Barriers: Certain building materials can get in the way of weaker signals like Bluetooth. Metal, bulletproof glass, concrete and plaster are particularly bad, and marble, plaster and brick aren’t great easy. So if you’re really struggling with interference, your first step should be to move your Bluetooth devices away from these materials. That means no brick walls between you and your devices, and definitely no metal desks!
  2. Change Router Channel: If you have an Apple router and you’re constantly getting interference with your WiFi, try rebooting it. Upon restart, the station will search for a new channel. Specifically, a different channel than the one your Bluetooth devices are using to communicate. If you don’t have an Apple router, you may need to instead go into your router settings and try changing the channel manually. Experiment with different channels to see which one works best.
  3. Move Closer to Your Router: If you often find that you’re getting interference when talking on a wireless headset while on a WiFi call (you’ll know because you’ll hear static), try moving closer to your router. This will give you a more robust WiFi connection, so the Bluetooth frequency can’t overpower it.
  4. Get Away From Microwaves and Fluorescent Lighting: Both emit frequencies of 2.4GHz, and moving away from them will distance you from the source.
 Wrapping it up 
At the end of the day deciding to go for a bluetooth thermometer is all about what you need.
If you’re primary goal is accuracy and range, then for now we have to recommend sticking with a reliable WIFI thermometer like the Maverick ET-733. If you need get reliable range passed around 50 feet then proceed with extreme caution.
On the other hand if you are prepared to risk having a few issues with bluetooth, but like the idea of having your temperatures on your phone, and an app that keeps getting improved then bluetooth is a good option.
