Help needed, controlling flow temp without controller

[psolarcz]

Could you please let me know if it's possible to set flow temperature without controller using ebus (vrc350 , 470 etc) ?

I've tried to add :

w,,SetTempDesired,Solltemperatur setzen,,,,01,,,temp0,,,

to hcmode.inc file but it was not included:

I tried to include mcmode also - I found this on some forum but it also failed:

I think I made some progress but this still doesn't work. I included mcmode.inc

Write commands are accepted and I can see values have changed when I execute find -w ... but when I read - old values are still visible.

ebusctl write -c bai FlowsetHcMax 74 done

ebusctl write -c bai SetTempdesired 45 done

pi@raspberrypi:/etc/ebusd/vaillant $ ebusctl find -w bai FlowsetHcMax = 74.00 bai SetTempDesired = 45

pi@raspberrypi:/etc/ebusd/vaillant $ ebusctl r FlowsetHcMax 75.00 pi@raspberrypi:/etc/ebusd/vaillant $ ebusctl r flowtempdesired 50.00

you can force the reads

[psolarcz]

If you meant read -f - I also tried but it's the same - old values.

I saw you also tried in other thread to set FlowsetHcMax - did you manage to change it ?

[john30]

please send the whole configuration directory to ebusd@ebusd.eu and let me know the ebusd start parameters, then i can check it for you.

@psolarcz , did you make progress and found a solution ? I have the same context : boiler without controller, and i m looking a way to control boiler through ebus.

[minscof]

up : any news about a way to modify temperature without controller ?

Is it possible to sniff ebus frames between a contoller and a boiler, to find out the update commands ?

[john30]

ebusd does that automatically, see the grab command

[Dinth]

@psolarcz whats the expected difference between FlowsetHcMax and SetTempdesired. My boiler only has the former variable, SetTempDesired is completely missing from the configuration.

@psolarcz Did you make any progress on this?

This is an old issue but I might have a solution for it.

I am using ebus adapter v2.2 with NodeMCU (ESP-12F) and RaspberryPi Zero W.

Here is my EBUSD-OPTS: EBUSD_OPTS="--scanconfig -d ESP_IP:ESP_PORT --generatesyn --accesslevel=* --logfile=/var/log/ebusd.log --enablehex --latency=10000"

I send setmode as hex command and here is the command. ebusctl hex 08b510090000xxyyffff00ff00 xx is (FlowTempDesired x 2) in hex format and yy is (desired domestic hot water temperature * 2) in hex format.

Here is my ebusclt i version: ebusd 3.4.v3.3-51-g57eae05 update check: revision v3.4 available access: * signal: acquired symbol rate: 32 max symbol rate: 75 min arbitration micros: 41 max arbitration micros: 509 min symbol latency: 0 max symbol latency: 30 reconnects: 0 masters: 2 messages: 229 conditional: 0 poll: 6 update: 9 address 03: master #11 address 08: slave #11, scanned "MF=Vaillant;ID=BAI00;SW=0306;HW=3302", loaded "vaillant/bai.0010006101.inc" ([PROD='']), "vaillant/08.bai.csv" address 31: master #8, ebusd address 36: slave #8, ebusd

I hope this helps.
