[Compare] DSMR P1 Port splitter

[Dijker]

As I see sometimes people struggling with multiple P1 devices,

Maybe create a topic with different splitters and review them?

I have found these:

• https://smart-stuff.nl/product/p1-bridge-versterker/ (Active, I have this one and it works for me!)

• https://www.tech4ushop.nl/p1h-005.html (via Topic [APP][PRO] Plugwise Smile P1 - Dutch and Belgian Smart Meter Reader - #189 by Gigi9 )

• P1 Splitter - SmartGateways.nl (Passive, This one did not work for me )

I had tried a few different P1 splitters before, but none of them worked properly with my “Zonneplan” P1 dongle.

Recently I noticed that Smart Gateways now offers an active P1 splitter, and this one does work

flawlessly with both the Zonneplan dongle and the Smart Gateways smart meter WiFi gateway.

In short: with the active splitter from Smart Gateways I finally found a stable solution. Definitely recommended if you want to connect multiple devices to your P1 port!

I have found these:

• Actieve P1 Splitter (Active, I have this one and it works for me!

And the splitter is behind 2 Homey Energy P1 dongels chained…
It works!

I use the 4-splitter (Tech4U P1H-006-C Actieve P1-poort Splitter – 4 Modules | DSMR 2, 4 & 5, e-MUCs-H, A1 Compatibel):

• Zonneplan P1 meter
• Raspberry Pi 3 with P1-monitor application
• KlikAan ICS-2000
• Sessy P1-meter

Works like a charm.
