I got a reply from Plugwise. Apparently the meter I have has a P1 port that isn’t “pure” enough. The data that it’s passing isn’t “low” or “high”, so it’s seen as corrupt and is therefore unreadable for the Smile P1.
They also said that this problem of “unpure” P1 port persist with most of the newest smart meters. They give two options to mitigate it:
-
Contacting the installation company to install a different meter (i.e. I think an older model smart meter with a pure P1 port.
-
Using an Active P1 Port Splitter, which “purifies” the data so that the Smile P1 can read it. With an extra benefit that you then have an extra P1 port in case this is needed. They recommend using this one: https://www.tech4ushop.nl/p1h-005.html. They also said that it’ll work.
(This is translated from Dutch to English)
The first option is very time consuming. So I’ve ordered this splitter (though I’m a bit salty that I need to spend extra cash (not just for the splitter, the power and cable you have to purchase separately. Plus it’s an extra socket I need to use in the utility closet). Once my order has arrived and I’ve installed it, I’ll post an update. Fair warning, the webshop doesn’t offer the smoothest shopping experience.
I did send Plugwise an email back stating that I hope they do something to their firmware, since it’s ridiculous that I have to by an add-on product from a third party to make their device work as advertised.
