Track temperatures from Signals, BlueDOT, and Smoke Gateway on your smart device.

BlueDOT utilizes your smart devices' Bluetooth to receive information with a communication range up to 95-feet line-of-sight. You can connect up to 6 BlueDOT devices to ThermoWorks BBQ app to set alarms, track min/max, and collect graph data.

Smoke Gateway connects to the internet via Wi-Fi to transmit and store information in the cloud. This allows ThermoWorks BBQ app to review your temperatures, receive alerts, and view graph data from anywhere.

Signals uses both Bluetooth and Wi-Fi, which allows for easy setup and different modes of connecting to Signals, so you can track your cook in any situation. Bluetooth allows you to connect directly to your phone or tablet, up to 95-feet line-of-sight, so you can use Signals if there is no internet connection. Wi-Fi allows you to track your cook through the internet and cloud from anywhere. Signals switches automatically between the two to give you the best experience.

You can connect multiple Signals, Smoke Gateway, and BlueDOT devices to ThermoWorks BBQ app simultaneously, giving you an overall dashboard of your temperatures.

I’ve had my gateway for a while now and the unit has never worked as advertised. I updated, as suggested and the device worked once and began to malfunction again. They also suggested network adjustments and that failed as well. The device is useless with WiFi. I am tired of companys building and selling defective devices on my dime. I work too hard to just give money way. ThermoWorks, you need to make this right us.

Good app, not perfect

I recently purchased the Signals device. Until now I’ve been using the Weber iGrill. The decision to go to the Signals product was the ability to connect via Wi-Fi. The Bluetooth range of these types of devices is not that good. I had to work some magic to monitor overnight smokes with just Bluetooth. Wi-Fi makes things so much easier. I feel for all the cooks who didn’t have this convenience even a few years ago.

This app works good now that I have it figured out. Coming from the Weber app things are similar, just some information is in different places. For example trying to monitor the battery charge of the unit I think takes too many steps. I think that important information should be readily available on the home screen.

One thing this app needs badly is an AppleWatch companion app. Again see the iGrill app. That is an example of a watch app done right.

In summary, if you cook on the grill you need a trusted thermometer. In this day and age it should be Wi-Fi compatible. Signals is an excellent option offering quality hardware and a pretty good app to go along with it.

Happy Father’s Day

Family purchased the ThermoWorks Signals for my Father’s Day gift. Boy do I love it! Smoking a brisket for 15 hrs overnight. The alarms keep me feeling safe and able to take a quick glance once in awhile. Two requests: night mode to change the background to black. And two, ability to set my own alarm sound. The built in sound is too common. Would love different sounds for each channel’s low and high alarm.
