For my install I have the ESP8266 mounted outside of the meter box. The LSR circuit is on a longish cable. The cable runs through a small hole in the lid of the meter box i.e. outside of my house. There is no ingress from the inside of my house to the meter box besides the mains power cables.<br><br><br>Sent from ProtonMail mobile<br><br><br><br>-------- Original Message --------<br>On 24 Aug 2021, 17:44, Mark Beckett < m.beckett@amuri.net> wrote:<blockquote class="protonmail_quote"><br><html>

Who says opening the meter itself, especially when placing a light sensitive
component on top of it? But you do have to open the metering enclosure
on the outside of the house, stick your gimmick onto the meter lid, and
then get your signal out of that enclosure.
