Development wise I’d say they are both quite similar - adding support for Husdata or “raw” CAN messages coming from rego8xx unit. However, the Husdata interface is well documented so implementation is more straight forward, while AFAIK there is no public documentation on “raw” rego8xx CAN messages so supporting the later would involve more error and trial.
Additional question - did you have to issue any commands on the Husdata interface or did you simply connect and data start to arrive?
Just hooked it up and the data started to roll in. I have an issue with not being able to send back data though.
I’m a bit confused about the readings you provided. There a couple of reading that seem to come from radiator return, but the values are alternating from 45 to 90. Since there is no timestamp associated with the values, do the below values make sense to you?
XR000101C2 => Radiator Return = 45°C
XR00010384 => Radiator Return = 90°C
XR000101C2 => Radiator Return = 45°C
XR00010384 => Radiator Return = 90°C
XR000101C2 => Radiator Return = 45°C
XR00010384 => Radiator Return = 90°C
XR000101C2 => Radiator Return = 45°C
Other readings seem more consistent:
XR000B0380 => Hot gas / Compressor = 89.6°C
XR0006FF93 => Brine Out / Condenser = -10.9°C
XR0006FF94 => Brine Out / Condenser = -10.8°C
XR0006FF96 => Brine Out / Condenser = -10.6°C
XR0007FFDF => Outdoor = -3.3°C
Please let me know.
Hi,
No - they make no sense at all 
I haven’t actually started to dig into the data yet. I have not even figured out the java code for parsing the hex values. When you found out the values, you didn’t perhaps use some java code that you could share ?
No, I decoded the values based on the provided data sheet, consider the first two entries within provided readings:
XR000101C2
0x0001=reg Radiator return of temp type (0)
0x01C2=data (0x01*256)+0xC2 = 450 = 45 deg C
XR00010384
0x0001=reg Radiator return of temp type (0)
0x0384=data (0x03*256)+0x84 = 900 = 90 deg C
I quickly checked the Husdata interface and it seems quite affordable, specially if you compare it with the canusb or can232 interface - therefore I might try adding support for the Husdata within the rego binding itself, but first would like to understand the provided values. Beside radiator return, do other values make sense (outdoor, …?). And do you have any clue why radiator return is alternating? What is the expected value?
A bit unsure what values in my unit that I should check for “Brine out”. However, I made a new dump with (what I can see) more stable radiator values? Still strange values?
If this connection type could fit in your binding - it would be fantastic.

XR0007FFE9Hi, I’m pretty new to the OH world so please forgive my noobness. I’ve managed to connect to my Bosch Heatpump (with a rego800) and see the CAN traffic (decoded by another protocol) on a RPi.
What i don’t get is how to have OH see my 8device USB2CAN as a serial/input. Can you elaborate please?
Thanks
Please find a pre-alpha binding with support for Husdata here.
Download the jar and put it within the addons folder. Navigate to the Paper UI, make sure you have “simple mode” on for the “item linking” and add a new thing, select RegoHeatPump binding, than the Husdata thing, set the serial port your interface is connected to the computer. Within the Control view of the Paper UI you should see some channels with values popping up (only a couple of channels are added):
"Radiator Return" = sensorValues#radiatorReturn
"Radiator Forward" = sensorValues#radiatorForward
"Heat carrier Return" = sensorValues#heatFluidIn
"Heat carrier Forward" = sensorValues#heatFluidOut
"Outdoor" = sensorValues#outdoor
"Indoor" = sensorValues#indoor
"Brine In / Evaporator" = sensorValues#coldFluidIn
"Brine Out / Condenser" = sensorValues#coldFluidOut
"Hot water 1 / Top" = sensorValues#hotWater
"Hot gas / Compressor" = sensorValues#compressor
NOTE: binding is NOT tested so I don’t expect it to work in the first try/run. Please set logging to debug for the “org.openhab.binding.regoheatpump” package and please share the log so I can see what is going on.
If you need any more details on how to setup and/or test, please let me know.
Additional note - the binding does not yet initialize the interface so please do so manually and than configure the binding as described above (when data is already coming to the serial port). And please disable debug output on the interface.
Did some testing with provided values and got something like:
Please give it a spin and let me know how it goes. I’ll add more channels + additional (setup) handling.
Not sure what you mean “decoded by another protocol”, but if you are able to get/read CAN messages on a RPi (or any computer for that matter), you are all set-up
I’d say that the USB2CAN adapter registers itself as a virtual serial port (i.e. COMx on Windows) and you can access it as any other serial port. In order to read CAN messages, you first need to setup the CAN (details can be found here).
When you have access to the CAN via serial, it is only a matter of decoding the received values.
Hope I got your question right, otherwise please let me know if you have any questions or comments.
Wow - fantastic!
I’m just about to download it - two quick questions:
I assumed the Husdata interface is connected via serial port. Can you please provide more details on how you are connecting to the interface?
Not sure what you mean by “simple mode”? The binding is currently expecting data to arrive in the following format:
XR0001018C[Carriage Return + New Line]
as specified within the provided document - the “Communication structure”. Please let me know if this is not the case.
The interface is attached directly to an RPi which are located next to the heat pump. My openHAB server is located in another location and connects to the RPi via IP/Port. On the RPi the daemon ser2net is responsible for sharing the serial port over TCP/IP. Works flawless.
Oh, I mean if it is possible to use it on my openHAB that does not run in Simple Mode (for Item creations). But I’ll gladly switch to simple mode in order to test this (I guess all Things and Links to Items in items-files will remain untouched).
Simple mode is only used for convenience - so if you turn it on before you add the serial/ip Husdata thing, it will create the links for you (those that can be seen on the screenshot from my previous post). You can turn it off after you add the thing, or manually add items if you prefer that way.
Please re-download the binding, you should have the option to add “ipHusdata” thing and select ip/port. Since I just added it, it is not tested 
21:04:00.867 [WARN ] [ore.thing.internal.ThingRegistryImpl] - Cannot create thing. No binding found that supports creating a thing of type regoheatpump:ipHusdata.
is binding name regoheatpump so debug line would be?
log:set DEBUG org.openhab.binding.regoheatpump
?
Forgot to add the ip thing into a list of supported things, please re-download and try again, sorry for this.
No problem at all
First everything looks good:
21:15:14.165 [INFO ] [me.event.ThingStatusInfoChangedEvent] - 'regoheatpump:ipHusdata:487fff1b' changed from UNINITIALIZED to INITIALIZING
21:15:14.169 [INFO ] [me.event.ThingStatusInfoChangedEvent] - 'regoheatpump:ipHusdata:487fff1b' changed from INITIALIZING to ONLINE
21:15:14.170 [INFO ] [.regoheatpump.handler.HusdataHandler] - Rego controller connected via 192.168.0.26:2001
Then I get:
21:18:26.827 [WARN ] [.regoheatpump.handler.HusdataHandler] - Still no Carriage Return + New Line received, resyncing.
I have enabled debug, but as far as what I can see, this is what gets written.
