Where to obtain J13 connector

Open Jochen0x90h opened this issue 5 years ago • 3 comments

Hi! Where do I obtain the connector that connects to J13 inside the Rotex control unit? Thanks!

I'd like to try to connect the Rotex HPSU Compact to OpenHAB, but first want to see if I get CAN working.

EDIT: It seems the connector is already present in the HPSU and is plugged onto the controller board. Next question: How to deal with the terminating resistor of the CAN bus?

Hi Jochen, no need for a terminating resistor. In my case (Raspi with PiCAN2 board) it is working without.

And if you want to use openHAB, sou should use this fork: https://github.com/Spanni26/pyHPSU This repo is not maintained anymore.

Thanks. Maybe I use an MQTT server like mosquitto, I'm still in the "research phase" how to do it. Homie, a convention for MQTT, gained my attention: https://homieiot.github.io/ In this case I would need an interface between the HPSU and MQTT.
