Does anyone have some experience connecting a Orcon Mechanical Ventilator MVS15 to Domoticz?

With Rf or wired?

I prefer RF but wired is an option if it can be combined with existing RF

Orcon is close to the Itho implementation and at some point in time it might be possible to control the device via RF.
Until then you could use for example RFLink and its GPIO pins hardwired to the Orcon remote.. that way RFlink is pressing the buttons for you and you can control the system via Domoticz.

@pvangorp

I have the same Orcon at home, and I have made some progress to make an hardwired connection.

So far I did the following;
1. Purchased: additional remote control, flexible flat cable plus PCB, PiFace 2
2. Programmed a couple of thinks in Python, and I control the Orcon via the command line

There are few problems that need to be solved;

1. There is still some current leakage, as the used out connections on the PiFace 2 are constantly on, but at a very low level. This drains the battery.
2. On the Python side more work is to be done; as the outputs on the Piface 2 should send out a 1 sec pulse and go back to the off state

Maybe you, or someone on the board has an idea how to solve the first issue.

Thans for your sollution. Should be easier with RFLINK 868.

For your python:

import time

abort_after = 1
start = time.time()

while True:
delta = time.time() - start
if delta >= abort_after:
break

Thanks for the Python code. Will give it a try.

I also prefer to do this via rf 868, but as mentioned by Stuntteam this can take a long time.

I'm no pro in reversed engineering. But there is an (I think) debug/program interface on the pcb that maybe can use to readout some data.

Is there already somebody that has try this way?

It's a old toppic but i'll give it a shot ;-)

Can you provide a scheme hoe to wire what to what. and how you get it work? I have a extra rf remote what do I need more?
