on the diagnostic page of the boilers UI, the raw voltage of the input is also displayed. |

tried to set writable parameters via ems-esp ui -> working, Decimal values for voltage not possible (example max :9,5V), When set via BoilerUI, the value is correct in ems esp entities. Is there a range checking for setting any values ? EM100 seems to be missing in mqtt.. |

Fixed the mqtt. For the voltage setting, please log while setting a voltage via ems-esp webui. I have set no limits, we have to see twhat the device gets and replys. |

this value is is called IO1 Power Monitor output (27 % at time of trace in Boiler display), currently not yet in EMS-ESP for this module. extension(0x15) -B-> All(0x00), ?(0x0936), data: 1B (offset 5) ==== Volttage Input of EM100 (not Entity on EMS-ESP for this) 000+17:41:03.421 N 1858: [emsesp] extension(0x15) -B-> All(0x00), ?(0x0936), data: 25 (offset 5) === |

Hello,
is / should it be possible to set flow temperature for systems with external temperatur control, as it is possible with the em 100 module.
This module is used, when an external (non EMS) control needs to request a flow temperature. EM 100 is wired via 0-10V.
I would like to achive this with the EMS-ESP, instead of going through 0-10V output and into EM100.
Boiler Type GB192i.2
Thanks, Philip
