Why do you want to set the flow temperature? You have a thermostat that sets boiler flow temperature according to the wanted room temperature. Just send the value to thermostat/seltemp (selected room temperature) and the thermostat calculates and set the boiler flowtemp. |

There are 4 heating cirquits with seperate controls / thermostats on an external Wago SPS control. There is loads of functionality implemented on this control, that is currently not possible with standard thermostats. The external control collects the maximum selected temperatur from single room controls and calculates/reduces the supply temperature taking sun influence, room priority, open level of single room valves into account. The goal is, to keep the flow temperature as low as possible. The maximium temperature calculated by these 4 heating cirquits needs to be sent to the boiler as flow temperature. EM100 ist the moduls for this, I still hope, this might me possible with the EMS+ gateway. As I have not seen any reference here to this new Boiler type and the GW show a different model, I have uploaded the support data. --Philip |

The boiler types are identified by the product-id, the name is only what have been reported as this product-id. But same product-id normally means same functions. Same for BC400, it shares product-id with UI800 and is mainly compatible with RC300. For the missing values of heat exchanger temperature: there are two unknown telegrams from boiler 0xD7 and 0xD8, maybe in one of these the value is published. Or in 0xE4, there are some unknown temperatures fields. Read the actual temperature from the BC400 and log > 1 minute the telegrams, maybe we find the value. |

I have started the log, while the hydraulic seperator temperature was 39.4 C, 19:31 The BC 400 shows a temperature 'Vorlauftemp. Wärmezelle' with the following values: 52.7, 58.7, 62.1. ems-esp:$ wems-esp:$ waems-esp:$ watems-esp:$ watcems-esp:$ watchems-esp:$ watch ems-esp:$ watch oems-esp:$ watch on Thanks, Philip |

Thanks, that's the right way to find the values. We have the seperator in E4 offset 25 and (less often) in E3 offset 11, the heatcell in E4 offset 23. Please first check with custom entities (factor: 0.1, UOM: °C): |

Wow ! It works fine. I am really impressed what this software can do ! The following translations are used on the BC400. Regarding the shortnames: hydrseperator (online translate for hyraulische weiche), heatcell.. Vorlauftemp. Wärmezelle Aanvoertemp. warmtecel Flow temp.hesating block Temp. départ corps de chauffe Temp. mandata scamb. pr. --Philip |

I've added the values to my dev at https://github.com/MichaelDvP/EMS-ESP32/releases/tag/latest |

I have installed yout test build, and the new values are shown with correct values. Thanks ! |

Just to let you know - I installed it as well as I got a GB172i.2 with a BC400 - but with this version a lot of values got lost (the UI-800 version filled all of them): thermostat_data_building Would be nice if you could revert it or doublecheck why they are missing now - especially setting the wwcharge and wwmode is no longer possible! Had to revert back to 3.6.2 By the way - hc1_mode writing is not working in any of these - any ideas? (manual/auto) h3ll |

thanks for reporting the mode issue (#1414) - We'll look into that. @MichaelDvP can comment on the missing values. I've had that issue a few times before and had to 'Restart' EMS-ESP to fetch all the device entities. |

Ok - thank you for the hint - back to latest version - except for the boiler all values returned with a restart. I'll have an eye on the a few of them, could be they appear over night. As I'm new to this I'll always restart after flash :) Thanks! |

Hello,
a newly installed Buderus Boiler with building BC400-FO Control and Freshwater Station, seems to be missing some values, or the value names are unclear to me. For example, I am looking for the hydraulic seperator temperature. (optional, but installed here).
Is there any experience with this type of device ?
Also with the FS27/7 values seem to be duplicate, related to WW. Use which device to control WW ?
UI-800 of ems-esp seems to be the BC400 factory buildin to the boiler front panel.
SM100 ist the freshwater station FS27/3E.
still missing, not yet installed/connected:
Solar Station, EM100 to set flow temperatur for external temperature control.
External control will be needed/used, because Buderus currently does not supply KNX10 and seems to be forcing users to cloud base / wifi single room thermostats.
