[Tweet](https://twitter.com/share) ### See what people are up to with Opto 22’s new edge I/O module. [*groov* RIO](https://www.opto22.com/products/groov-rio) has been available for a few months, and people are already surprising us with how they’re putting it to work. Here are a few of the amazing examples we’ve seen from our early adopters. [**Grantek![Grantek](https://lh4.googleusercontent.com/L6wI0-n1Bf3FNb5HYMUj6arjN-5cyn1RAd6ZjJisYHuWW3uWFmNxSEPZLCR4nU-X2-4TgC1-ukWSm5IoWP3FkK9ZvGYY4-F0S8KIABfqqr8kNSWZ6PRhnM-wI7beCKARaZa2O40M)**](https://www.opto22.com/community/opto-partners/grantek) “RIO gets me I/O on the edge… that isn’t a PLC” -- Doug Yerger, Principal Engineer *Industry:* Material Handling *Application:* Granular temperature monitoring for intelligent automated storage and retrieval system (ASRS) *Solution:* Grantek used *groov* RIO to design an efficient, easy-to-install system that collects temperature data across an entire warehouse and delivers it directly into their customer’s Ignition SCADA system using MQTT. They leveraged *groov* RIO’s power over Ethernet (PoE) capability, so the system can scale affordably without power supplies or PLCs to add to the cost of labor and configuration. ![Automated storage and retrieval system](https://lh3.googleusercontent.com/EjSnHoeLvjIG__1lD8_fpeZ6o93YKHx3y1aclKv4NDtR4e7j_UWyMjHO1anfsMp8qt82-_O9ecOfdgZ3XwDMA3pFt-dxu3IiOx3ZNCw_FOSHlGtAHPQ37RBGNMjfJtVoSivEwHg5)*Image source: directindustry.com*   [****Leuze - Brazil (SI)****](https://www.opto22.com/community/opto-partners/leuze-electronic)[![Leuze](https://lh3.googleusercontent.com/gxvjIywjOx2hMKfXK39My8qUxmK0EuPh7aoWKTKbM2yx-C7-LMxZgEJIM867MSbvtzR27Il0ndPBRWd5JgL4faHCTFHXjQkqiCjedMwfFrSPYLDWM2PwJAO0YVqF8ctTmlkzPsjL)](https://www.opto22.com/community/opto-partners/leuze-electronic) “RIO is really, really, really easy to get online.” -- Felipe Villas Boas, Application Engineer *Industry:* Plastics manufacturing *Application:* Collect performance data from 80 different pieces of standalone equipment and move them into a central database for analysis *Solution:* Since these units lacked any comms interfaces, Leuze’s applications team developed a solution using *groov* RIO to read I/O directly from each unit, process the signals in Node-RED, and transmit the data to the company database. Done! In addition to that, with *groov* RIO’s internal and external storage options, they can buffer data locally in case the database connection is lost for any reason. **![](https://lh4.googleusercontent.com/Jh34C93DKWyTfi68Uxgs1tJ7XD2hZd4DGCE1WF-w2R2yQALs6fGkCrD_l3LE2DDsC8yLHHx7UYsuhF8_PPdd9BdFaa1ruTFwSd3rqg-R9ltMv5Bl9JWxycL_Y6kVRqyivFlLOiOq)** *Image source: manufacturing.net* [**MicroClimates**](https://www.opto22.com/community/opto-partners/microclimates)[![Microclimates](https://lh3.googleusercontent.com/T8Ii42eUk0O0vhu1OKTvRR_8C0yaXGfvAFW0jPs8PSxNFpSQKZQM5tfsitdgWki8WZKOQlU-3fYChMLhELYOyXF7ovJuh-Gn9GdsQibXX3klvmcKcubqB_GhzP0QMWwFp1YFPNDR)](https://www.opto22.com/community/opto-partners/microclimates) “Where EPIC scales vertically, RIO scales horizontally beautifully.” -- Loren West, CTO *Industry:* Agriculture *Application:* Indoor farming control and business intelligence product *Solution:* MicroClimates sells *groov* RIO as a Modbus microcontroller, packaged with onboard control software and a mobile HMI developed in Node-RED. For as little as $1000, their customers can add automated control of LED lights, environmental sensors, nutrient pumps, and more, using power over Ethernet to grow their automation incrementally as their operations expand. ![](https://lh6.googleusercontent.com/fuCgI6cjfq2S2pqtuZHSiGwvXilitc7z2SCj9i0wBz4M4k47BhbS99fyy8O7oK0TFOyl41LTOLYQSqnyR10BdK7F49ebJmDmE_kQH4qfJXV0Nc0ZQ56Uqh62ZfEXFfke_PsAw3hB) *Image courtesy of MicroClimates* Each *groov* RIO module also sends data to a local business intelligence server, which acts as the remote gateway to MicroClimates’s cloud systems, allowing users to manage multiple sites from anywhere.   [**Optomation Systems![Optomation](https://lh5.googleusercontent.com/njrvzKfl6dHH2LVLJp6jdkRi8v1QtOsVM8WEoVI6EyQVTO0QfkbVECo6eiBQCrXuhOiRM1PF5_6EbJW2eiklgxsP_TastJsVN_eWBoehMJR6gcCnNAWGzPcwxWCKaYTI3SE9hKcD)**](https://www.opto22.com/community/opto-partners/optomation-systems) “RIO has the resolution they need without having to calibrate over and over.” -- George Mitchell, Technical Director *Industry:* Automotive Manufacturing *Application:* Integrated assembly line calibration test and reporting system *Solution:* Optomation designed a rechargeable mobile test harness that uses *groov* RIO to capture readings from vehicle sensors, simulate outputs to the vehicle dashboard, and display and record test procedures through a mobile interface. *groov* RIO reports the results to a quality control database located in Italy and to an off-site production database in Spain. ![](https://lh6.googleusercontent.com/Uq5KwboItE9kXJ7Z5fA559li5f_xAKXTsNH_SQj36uITNhDghzT0mfFL6pjpGikglHfoCf9H09jltSvgpQgJMWj8WMmVBNT1cYUc3fGPeiVs9G8cLsKYqP3oQQcKrrAh3nb2wJ-0) *Image courtesy of Optomation Systems*   Edge I/O opens up new possibilities for automation that pave the way to a more connected future.
