2 months ago The ems boilers store the last errors in telegram 0x10 and 0x11, ems+ in 0xC2, seems the heatpumps uses a different telegram type we don't know. The actual error is published in telegram 0xBF, the boiler handlers indicate that it was received. But it's difficult to read the BF, it is only published on errors and reading always gives an empty answer when there is no error. Try to log the telegrams and initiate an error. maybe we can see what telegram the heatpumps use. Or you can use custom entities to monitor 0xBF device 0x08, telegram 0xBF: offset 0: UINT8 device id of error reporting device offset 1: UINT8 product-ID offset 4: UNT8 errortype enum: info, locking, blocking, system, reset offset 5,6,7: 3 digit ASCII code offset 8: UINT16 errorcode
But custom entity will only show up on error and is removed when the error is gone. It's not a permanent publish.

On my Buderus WLW186 heatpump with ems-esp 3.7.0-dev.32 I have successful communication, but failures and errors of the heatpump will not be indicated at the ems-esp. I have "created" a failure by disconnecting the outside temp sensor and the failure is correctly indicated a the hp and the rc, but no information or failure status indication in ems-esp...?! Is something missing here or are custom entities required to get the failure status of the hp...?
