Hi, i have the same problem. Anything new?

Calenta DS 15

Find the solution in an other thread:

uart:
  id: uart_bus
  baud_rate: 9600
  tx_pin: GPIO15
  rx_pin: GPIO13
  stop_bits: 1

I changed the Pins on my w1 mini

Same problem for me :-)

Probably there is lot of type of Boiler, there is SW Rehema Recom for monitoring Boiler, after install it and connect monitoring working via USB-TTY adapter and Recom Identification is "PCU-02/03 (P3)" there is condig folder contain XML file for this Boiler Rehema-Recom-5-2-0_config_xml.zip

I've been trying to get this running with a Remeha Avanta boiler with no success so far. It seems that this boiler communicates in a slightly different way, which was presumably altered in the dietrich_calentaV1_P5.h file. I've tried to apply the same fixes here but I still keep getting CRC errors. It does seem like data is coming through, though running it through a HEX converter returns a garbled mess.

Can anyone point me in the right direction what else to change? A bit of sample data is attached below. I am running a D1 mini, with UART connected to TX - GPIO1 and RX - GPIO3.
