Recovair 360 behind VR32/3

[maxp1256]

Hello!

What's the current state about the communication with this setup and ebusd? Should I install 2 ebus-adapters or is there any configuration-option to get it working with one adapter in the "big" bus with multimatic (after VR32/3)?

Hi, generally it's possible with a single ebus-adpater. you need to rename the recovair 08.recov.csv file to (add).vr32.csv (so of course this means locally hosting your configuration files) and adjusting the latency when you start ebusd to 100000. There are quite a few posts on the discussion forum of ebusd (rather than this configuration files site), you may wish to start here:

Thanks @JonesGW-MGD seems to be working as desired! Perfect!

I'd like to spend some documentation for future use:

First I added --latency=100000 and --scanconfig to my EBUSD_OPTS in /etc/default/ebusd

restarted ebusd

started listen in another ssh-session: (-p 8889 is optional because I'm using another port for ebusd)

ebusctl -p 8889 listen
listen started

recov HeatRecovery = on
recov SupplyFlowActual = 179
scan.08  = Vaillant;BAI00;0703;7401   --> scan.08 = 08.bai.csv. 
scan.15  = Vaillant;70000;0614;6903  --> scan.15 = 15.700.csv
scan.38  = Vaillant;V32;0117;9802 --> scan.38 = 18.recov.csv <--- for my Recovair 360
recov FrostProtection = off
scan.52  = Vaillant;VR_70;0109;2903 --> scan.52 = 52.vr_70.csv
recov BypassPosition = 0.00
recov ExhaustAirHumidity = 45.31
recov SupplyFlowActual = 181
scan.f6  = Vaillant;NETX1;4035;5703

searched the matching configuration files in the git repo and downloaded it with wget and the raw https link from github to /var/ebusd/config/

-rw-r--r-- 1 root root  6267 Feb 12 20:54 08.bai.csv
-rw-r--r-- 1 root root 68823 Feb 12 20:54 15.700.csv
-rw-r--r-- 1 root root  6643 Feb 12 20:29 38.recov.csv
-rw-r--r-- 1 root root  1187 Feb 12 20:53 52.vr_70.csv

added --configpath=/var/ebusd/config and removed --scanconfig from /etc/default/ebusd

restarted ebusd

and everything was working fine :-)

Great!
