Solar pump state

[swenrengers]

Is it possible, to read the actual state of the solar pump?

Vaillant autoMatic VRS 620/3 I can't finde the corresponding value...

By looking at the configuration file (https://github.com/john30/ebusd-configuration/blob/master/ebusd-2.1.x/en/vaillant/ec.solsy.sc.csv) of the ec slave: You could either read out the overall runtime of the pump by looking at the message CollPumpHRuntime1 / CollPumpHRuntime2, but that will only provide hourly granularity. Otherwise the message SolCollPumpED1 / SolCollPumpED2 could be what you are looking for as it gives out a percentage at which the pump is actually running. However this might be not useful as it may not work on non-PWM based pumps or stay at a percentage even though the pump is off. If none of the above message cover the use case you need, you may have to look at messages, that have not been decoded yet (https://github.com/john30/ebusd/wiki/3.1.-TCP-client-commands#grab) and decode them yourself.

Maybe I can help: I found the following document: https://ebus-wiki.org/lib/exe/fetch.php/ebus/vaillant_ebus_v0.6.0.pdf With this I was able to decode some unkown massages e.g. 10ecb5040121 / 050600005f00 und startet a file "scmode.inc" based on "hcmode.inc" with a massage Status02 # type (r[1-9];w;u),circuit,name,[comment.de],[QQ],ZZ,PBSB,[ID],field1,part (m/s),datatypes/templates,divider/values,unit,comment.de *r,,,,,,"B504",,,,,,, *uw,,,,,,"B505",,, r,,ScMode,Betriebsartabfrage,,,,01,unkown,,HEX:1,,,,Mode,,mcmode,,,Betriebsart,unkown,,HEX:7,,, r,,Status01,Statusabfrage,,,,0d,unkown,,HEX:5,,,unbekannt r,,StorageTemps,Speichertemperaturen,,,,10,StorageSensorSP1,,temp3,,,SP1,StorageSensorSP2,,temp3,,,SP2,StorageSensorSP3,,temp3,,,SP3,DiffTempSensorTD1,,temp3,,,TD1,DiffTempSensorTD2,,temp3,,,TD2 r,,Status02,Statusabfrage,,,,21,CollectorTemp,,temp0,,,Kollektortemperatur,SolProtection,,temp0,,,Solarkreisschutz,HeaterSorce,,scmode,,,Status,StorageLevel,,percent0,,,Speichpower,,percent0,,,Ertragsgüte r,,Gain,Solarertrag,,,,28,Gain,,U3N,,kWh,Solarertrag uw,,SetHWCLoad,WW-Bereitung,,,,27,StoarageLoadCircuit,,onoff,,,SpeicherladungKreis,VF1,,temp0,,,VF1,StorageLoadAktiv,,onoff,,,SpeicherladungAktiv uw,,SetSysParams,Systemparameter,,,,2b,PreDeaktivationTime,,minutes0,,,maxVorabschaltung,FrostProtectionDelay,,minutes0,,,Frostschutzverzögerung,TempIncrease,,temp0,,K,Temperaturüberhöhung,unkown,,HEX:4,,,unbekannt

The Byte HeaterSource appers in 3 different values scmode,UCH,0=off;1=solar;2=heater,,Solar Modus. If it is 1, solarpump is working.
