I'm really sorry to hear that you got a "smart meter." This is what I would do:

1. Install a shield cover such as this one: https://www.amazon.com/gp/product/B00OVJCPS6/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B00OVJCPS6&linkCode=as2&tag=electricsense-20&linkId=82e649ef66e93f1963eb084008e88400
2. Behind the wall where the smart meter is installed, I would cover it with Mu-Metal: http://www.4ehsbyehs.com/rf-protection/elf-blocking-mu-metal
3. Since I probably couldn't get all my neighbors to do the same, I would add a Faraday canopy over my bed: http://www.radmeters.com/HF-Canopy-box-shape-for-double-beds-from-NEW-DAYLITE-fr.html Along with floor mat: http://www.radmeters.com/Floor-mat-from-HNV80-double-bed-fr.html (These aren't cheap, but they last for a long time, and if you want the best protection, even from cell towers, I haven't found a better option. Remember to keep the pets out of your bedroom though.)
