Do I need an internet connection to get a smart meter?
No. You don’t need Wif-Fi or an internet connection to get a smart meter.
Smart meters send readings to suppliers via a dedicated smart network. It doesn’t rely on your home Wi-Fi.
But the In-Home Displays we supply are able to connect to Wi-Fi. In the future, if you choose to connect your display to Wi-Fi, you will see more detailed information in your Bulb account online.
Are smart meters dangerous to my health?
Smart meters use radio waves or a mobile signal to send meter readings to your energy supplier, on a par with baby monitors and mobile devices.
Public Health England consider this to be well within the allowed guidelines for wireless transmission devices.
UK Health Security Agency (UKHSA) - Smart meters: radio waves and health
Are some people sensitive to radio waves?
Some people report real and unpleasant symptoms that they attribute to exposure to radio waves. Considerable effort has been put into investigating this topic rigorously in recent years with research programmes funded by the government and academic bodies. The results of these studies have been published in the scientific literature.
The 2012 AGNIR review mentioned above included a chapter on the evidence for sensitivity to radio waves. AGNIR concluded there is accumulating evidence that radio wave exposures below guideline levels do not cause symptoms and cannot be detected by people, even those who consider themselves sensitive to radio waves.
This conclusion does not belittle the importance of the symptoms that people experience, but it does suggest causes other than those directly related to radio waves should be considered. The Health Protection Agency, a predecessor of UKHSA, published a review of the public health aspects of electrical sensitivity in 2005, which included comments on the management of affected individuals and evaluation of treatment options.
Well, they would say that, wouldn’t they …
ETA I had a first generation smart meter for years, now I’m on the second generation:
SMETS1 smart meters
SMETS1 meters were the first generation of smart meters, which energy suppliers started to install in 2013. They were fitted with the same kind of 3G sim card that you could find in a mobile phone, so they could update the supplier at set intervals.
The problem was, if you changed supplier, many of these types of meters stopped sending automatic readings.
SMETS2 smart meters
Since then, we’ve seen the launch of the next generation of smart meters, named SMETS2. These have all the same energy-saving features of the last generation.
But the added bonus is SMETS 2 smart meters are cross-compatible with other SMETS2-ready energy suppliers. The software used in these smart meters is able to exchange and make use of information from other SMETS2 meters. So if you switch supplier, you won’t need a meter exchange, and you won’t lose your smart meter features.
AFAIK, I haven’t been affected by radio waves …
