If you've been a long-time OptoBlog subscriber or have used Opto 22 *groov* products, you've heard about the MQTT technology included in *groov* EPIC and RIO.  We've even created a section of the website dedicated to [MQTT Resources](https://www.opto22.com/products/mqtt-resources) like white papers, videos, and technical articles to give you a better understanding of this popular protocol. One of the resources worth referencing is the [Getting Started with MQTT in *groov* Products](https://www.opto22.com/support/resources-tools/documents/2350-getting-started-with-mqtt-in-groov-products) technical guide.  This **comprehensive, structured user's guide** helps you make an educated decision about which of the MQTT clients and options in groov products are best suited for your application. The guide explains the features, differences, and configuration procedures of each. Plus, you'll find some additional resources to help you build out your MQTT network or make a pitch for using MQTT. Just recently, the guide has been updated to include changes made to the *groov* Manage menu. You'll notice configuration for both MQTT and OPC UA have been moved to a new menu button called "Data Service." The guide features illustrations and more details about these recent updates.

Opto 22's VP of Product Strategy, Benson Hougland, has often described Lake Powell ([which stretches from southern Utah to northern Arizona](https://goo.gl/maps/b9RwFXYFb9ny9Com8)) as one of his favorite vacation destinations. A houseboat vacation has become a family tradition that always took him "off the grid" for a week. This year was a different story. With a [*groov* RIO](https://www.opto22.com/products/groov-rio) edge I/O module outfitted with some temperature sensors, and the convenience of a Space X Starlink satellite internet system on board, this year's trip made for some memorable moments in remote automation.
