Re: Zehnder/Stork WHR Ventilation Unit

That would be cool. I have also a WHR930Luxe. I already can set the fan to 1 with a sonoff. I have also connected 4 DS18B20 to the sonoff OK that's a wifi switch I guess. so you don't have the RS232 protocol working? and you use the DS 18B20 to read the 4 air temps. I'd prefer to read the temps fro...

Re: Zehnder/Stork WHR Ventilation Unit

I have all the programming checked and working but getting no results. My guess is that the protocol description for the WHR930 is not compatible with the WHR930 Luxe which I am using. I get no response on the commands that I send to the unit. the send led on the USB<->RS232 interface is blinking wh...

Re: Zehnder/Stork WHR Ventilation Unit

After being injured for a long time I picked up this project again. I am not a python programmer so I only understand a small part of the code in ventserver.sh neither do I use domoticz: ventserver is running on a PI and the only thing I need is a (json) file with the temperatures. I have a WHR930Lu...

Re: Zehnder/Stork WHR Ventilation Unit

@ bizziebis Too bad I can't get it to work. Looks like I have no signal at the RS232 output from my WHR. When I measure, it only shows 0.7 volts on RX, and 0V on TX. When I open up a serial connection nothing changes in the levels. including your next post you say that you see 0.7 Volts on TX and 0 ...

Re: Zehnder/Stork WHR Ventilation Unit

Hi Rob, The domoticz controller (a raspberry pi, linux, cubietruck, or windows PC/server) does by default not have a R485 conversion. To get this working you'll need a RS232 to USB converter as by default the WHR930 comes with a RJ45 RS232 connection socket and not the default RS232 socket. For #2,...

Re: Zehnder/Stork WHR Ventilation Unit

Hi, Maybe I am going to ask some stupid questions/observations so please bear with me. 1) My WHR 930 has a RS232 interface, does that mean that a Domoticz controller has a RS485, otherwise this conversion is obsolete. or are you running Domoticz on a platform with a RS485 interface? 2) I run a Fibar...
