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/](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](https://www.tech4ushop.nl/p1h-005.html) (via Topic [[APP][PRO] Plugwise Smile P1 - Dutch and Belgian Smart Meter Reader - #189 by Gigi9](https://community.homey.app/t/app-pro-plugwise-smile-p1-dutch-and-belgian-smart-meter-reader/8012/189) ) - [P1 Splitter - SmartGateways.nl](https://smartgateways.nl/product/p1-splitter/) (Passive, This one did not work for me ) Also see: [![](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/2/d27eafd662e8528669b44d8760d489cd536643ac.png) ](https://www.tech4u.info/product-info/P1H/P1_port_splitters_comparison_v1.png) (No affiliate) Please add your experience / Advice below! ---

Ik gebruik een iungo p1 poortsplitter. Wel een oudere versie. [p1 poortsplitter 5.0](https://www.iungo.nl/nl/bestellen/i/505-p1-poortsplitter) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/8/c8d744e7ac2f430b90525d0dc7b63805b87d7f72.jpeg) ---

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](https://p1splitter.eu/), and this one does work ![Active P1 Splitter with 4 ports for Smart Meters DSMR on table](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/3/e3cdd7f52eb787f4de1f01b34b57dad33c64f398.jpeg) 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 use the 4-splitter ([Tech4U P1H-006-C Actieve P1-poort Splitter – 4 Modules | DSMR 2, 4 & 5, e-MUCs-H, A1 Compatibel](https://www.tech4ushop.nl/p1h-006.html)): - Zonneplan P1 meter - Raspberry Pi 3 with P1-monitor application - KlikAan ICS-2000 - Sessy P1-meter Works like a charm.
