Beginner problem with two Brink/Encon Renovent 300 units

[mstroeve]

I am trying to read data from two Brink/Encon Renovent 300 units which are configured in a master/slave setup and are connected using the ebus connection on these units.

For the reading I use a Esera USB Ebus coupler which is also connected. I found this mapping CSV https://github.com/dstrigl/ebusd-config-brink-renovent-excellent-300 Which I placed in /etc/ebusd/encon/3c.csv

When I issued the following command it seem to find the master and slave (37 and 56?).

/etc/ebusd$ ebusctl i version: ebusd 3.3.v3.3 update check: revision v3.3-4-g212b22d available signal: acquired symbol rate: 21 max symbol rate: 38 reconnects: 0 masters: 2 messages: 0 conditional: 0 poll: 0 update: 0 address 31: master #8, ebusd address 36: slave #8, ebusd address 37: master #18 address 56: slave

But when I try for example: ebusctl read -f SoftwareVersion ERR: element not found

it doesn't seem to work.

The strange thing is that's after a while an extra slave comes up with "ebusctl i": address 3c: slave #18, scanned "MF=ENCON;ID= ;SW=-;HW=-"

which seems to be te address mentioned in the csv file.

Any hints how I could get some read info from the master and slave unit?

how did you start the daemon?

[mstroeve]

ebusd -f --logareas bus --loglevel info -d /dev/ttyUSB-Ebus -c /etc/ebusd/

[john30]

hm, your arguments to ebusd don't match your previous comment where the 3c appears as scanned device. this is usually only the case if ebusd was started with "--scanconfig". are you sure that you have only one ebusd instance running? check by issuing ps aux|grep ebusd

[mstroeve]

I checked my bash_history and I tried some other things I now have a reading. nice! But how can i read/write info from the slave unit as it seems I can only get info from the master

I deleted all the csv files from the mentioned GitHub repo all except 7c.renovent-excellent-400.csv

when i start the config seems ok: sudo ebusd --checkconfig -c /etc/ebusd/ 2018-12-30 13:03:37.093 [main notice] ebusd 3.3.v3.3 performing configuration check... 2018-12-30 13:03:37.118 [main notice] found messages: 75 (0 conditional on 0 conditions, 0 poll, 0 update) 2018-12-30 13:03:37.119 [main notice] ebusd stopped

and then I started Ebusd using: ebusd -c /etc/ebusd/ -d /dev/ttyUSB-Ebus

when I open ebusctl in a different ssh terminal I can fire the command read Aussenlufttemperatur and I get 9.9 which is the temp also shown on the display of the master unit.

[john30]

ok, so is there any issue left?

[mstroeve]

well I am trying to read values from the slave and master unit but I always seem to get the same value while the displays state different values for example (Ablufttemperatur) 19.6 and 20.

I tried the following different addresses using it a both -s as -d override address. But I always get 19.6 (or invalid address for some entries)

version: ebusd 3.3.v3.3 update check: revision v3.3-4-g212b22d available signal: acquired symbol rate: 18 max symbol rate: 40 min arbitration micros: 714 max arbitration micros: 1200 min symbol latency: 5 max symbol latency: 6 reconnects: 0 masters: 2 messages: 76 conditional: 0 poll: 0 update: 0 address 31: master #8, ebusd address 36: slave #8, ebusd address 37: master #18 address 3c: slave #18, scanned "MF=ENCON;ID= ;SW=-;HW=-" address 56: slave

[john30]

so the display shows 20 while reading from bus is 19.6? well this is just a simple rounding done by the display I guess.
