Here’s something that is relatively inexpensive to make that you can use to shield smart meter for temporary situations. (see video below) We recommend restoring analog meters on your home, however there are situations where a temporary shield would come in handy. These are not for long-term use. Thanks Amy for the video!
For longer term use, a shield using screen allows for more air circulation- here’s info on how to make one of those: http://www.instructables.com/id/Smart-Meter-radiation-shield
