Hi there, After years (10+) of trouble-free X10 in my house, I recently run into some problems with many rogue messages containing -after stripping the Voltage, Impedance and Noise levels- J SRQ. 'J' being the address and SRQ the X10 Command (meaning Status ReQuest) In my setup I've an PMIX as inter...

Right! Now its clear! And again kudos for the info and answers. I meant indeed node.js and C. In my HomeAutomation for controlling the lights by means of X10 commands I use a Pi to communicate over serial to the PMIX controller This is a USB-serial interface between a PC and the powerlines to transp...

Ah! OK, it begin to sink in now! This is *great* info. The only question I would have is how to send the CS=32.48\r info from Pi to OTGW. Is it a serial communication (do I have to set up a baudrate for example) or is there a pointer where I can find that specific info? Many thanks and have a great ...

Well, this is *excellent* information, Thanks very much. I will start to work on it, and keep it simple in the beginning. I can work with a temperature sensor on the return to the boiler to create a closed loop. But perhaps it doesn't need to be. I guess your suggestions is great to just lower the w...

Right, yes, I might have been confused, and you helped me a lot by stating that the proposed set-up (pi <-> otgw <-> boiler) will be the proper one. I've read that the otgw is now able to receive a simple on/off signal (from pi or thermostat) as well, so I can proceed with that for the moment. The n...

Hi, OK thanks, I reckon it can be done, yet not sure how. I've added a drawing reflecting my setup. Sensors reports plain temperature. The code in the Pi checks with desired value in the database and if needed opens the valve to the room and starts the boiler. I understand that I need to write my ow...

I hope the answer is yes as well, but until now it has been a bit quiet on this topic. That makes me feel that there is no such thing as a raspberry and/or arduino setup to communicate with Opentherm. Yet. I found this website: http://ihormelnyk.com/page/arduino_opentherm_controller in which the own...

Hi all, Reading for a long while this forum it seems that most of the contributors are far more advanced than I am. I still hope someone can point me in the right direction for my newbie question at hand. My situation is that I have 7 (room)thermostats in my house that communicates with a central un...

aha, same on me... I actually didn't see it, although I visited that page frequently, Never noticed that part, so thanks. I think my firmware is 1.3.1. Not that I have the impression it matters too much, but I will install on my Mac and see what happens. (btw... working to make an MQTT bridge for PM...

Hi Stefxx, Thanks for the reply, and yes I'm aware of it. My PMIX35 is attached to my Plug computer running Linux (of course) and will shortly move to a Raspberry Pi. It was just that I reviewed the manual, now published by Haibrain, that speaks about: 2.1 PMIX35 communicatie driver De PMIX35 is voo...

Hi giys, been out of HomeAutomation for a while but recently started up the PMIX35 again. Trying to get the comms going on a Raspberry Pi. I saw on the usermanual pdf that PMIX is supported by Mac (OSX) as well. I spent the best part of an hour to find software, but I failed. Does anybody knows if 4...

Aha, thanks, I'm pretty sure that the modules are transmitting on 866 MHz, but not quite sure. It is a bit mystic. I've ordered a KNX-RF USB dongle from Amber, should arrive any day now. Didn't cost a fortune (about €60) and I will try to get it picking up the RF signals and see what happens. Keep y...

Hi All, In my house I've installed Uponor wireless KNX thermostats in every room. They communicate with a Uponor C-55 systems that kicks off my heating and opens valves to a particular room. Works fine. But... ...I would like to receive the wireless KNX signals from the thermostats to the C-55 in or...

Hi Lukelle, Although I do not have an answer to your problem, I'm triggered by your project. Every now and again I'm trying to find some time to write soem c code to control the PMIX35. I'm not making progress due to time but also due to lack of the timing scheme of the PMIX and some basic understan...

OK, thanks. The routine for calculating the checksum is done, in my case, under C/Linux. That part I do understand. But still I keep strugling with the dim/bgt command. Sorry for being a pain, but I just don't see the logic in it. I think I miss some vital info on the command structure of the PMIX f...
