Protherm Skat support

[moskovskiy82]

Have a protherm skat (ekectrical). No external thermostat (but getting one if it can help - advice needed on Thermolink) The only needed option was to control the flowtempdesired setpoint.

$ebusctl f -d -v -c scan.08 id scan.08 id = prefix=21;year=20;week=38;product=0010023648;supplier=3100;counter=013480;suffix=N1

bai.prothermskat.inc is a csv from the https://github.com/john30/ebusd-configuration/pull/205 Only changed the naming for ExtFlowTempDesiredMin to a standard

Also modified the 08.bai.csv to include [PROD='0010023648']!load,bai.prothermskat.inc,,,

I have tried setting directly changing the register to writable but with no luck ebusctl write -c bai flowtempdesired 65

After read -f shows the old value

Also have included the solution from https://github.com/john30/ebusd/issues/179

Adding the line to bai.prothermskat.csv

wi,BAI,SetModeOverride,Betriebsart,,08,B510,00,hcmode,,UCH,,,,flowtempdesired,,D1C,,,,hwctempdesired,,D1C,,,,hwcflowtempdesired,,UCH,,,,,,IGN:1,,,,disablehc,,BI0,,,,disablehwctapping,,BI1,,,,disablehwcload,,BI2,,,,,,IGN:1,,,,remoteControlHcPump,,BI0,,,,releaseBackup,,BI1,,,,releaseCooling,,BI2

Afterwards

$ ebusctl write -c bai SetModeOverride '55;55;-;-;0;0;0;0;0;0' done

But still

 $ ebusctl read -f flowtempdesired
64.00

 $ ebusctl grab result all

Any chances in my case or it's a dead end?
