Easy to use, provides options for all kinds of scenarios (building owners vs employees). I have been able to automate much more than expected with this tool since we started using it in early 2015. Some features are still missing or not as intuitive like reporting dashboard would be nice option to add but nothing major yet! For small businesses looking for energy management software that can handle everything from building operations & security monitoring through billing/payments then OEP is definitely worth exploring further by doing some research yourself before making any decisions. We had multiple stakeholders involved which made our process cumbersome at times until i was introduced to Opeterry enterprise solution, now everyone knows what they need without me having to explain every step along way. I like that it is easy to use, has many options for different companies/types of buildings with different needs (such as residential vs commercial) and also allows you to do custom work when needed. There could be some training involved in order to understand how everything works but once trained it's very user friendly. We are able to control our energy usage more accurately than we did before using OE.
