I love how easy it was getting my information out from our old system into thermostat GRIDS! The interface does take some time if you are not familiar with using computers or tablets at all - but that's just because there isn't much available in terms of tutorials/tips online about this software so far as what should be done before hand etc., however once your comfortable enough everything runs smoothly!! My biggest problem has been finding reliable work order management (that integrates well wtihthermogrid) since we switched over several months back now; luckily though their support team have helped us through every step along way thusfar without fail :) Looking forward working closely together more efficiently than ever previously managed via paper process &.
