Duplicate '07' bytes in data about whr_930 HOT 5 CLOSED

Yes, I know …. I didn’t succeed in getting the layout of the code the way it should be. I don’t have time today to figure out how to correct that and it also will take some time for me to learn how to make the pull request. So, in the interest of time, maybe this helps: ==================================== def serial_command(cmd): data = [] ser.write(cmd) time.sleep(2) while ser.inWaiting() > 0: data.append(ser.read(1).hex()) # check for ACK and/or matching checksum here .............???? if len(data) <= 1: # always expect a valid ACK at least return None if debug: debug_data(data) if len(data) == 2 and data[0] == '07' and data[1] == 'f3': pass # just ACK by itself (on all "setting" commands, such as setting ventilation level, command x99) else: # valid respons should be at least 10 bytes (ACK + respons with data length = 0) if len(data) < 10 or data[0] != '07' or data[1] != 'f3' or data[2] != '07' or data[3] != 'f0' or data[-2] != '07' or data[-1] != '0f': warning_msg('Received garbage data, ignored ...') return None dat_len = int(data[6], 16) # if len(data) > 10 and dat_len > 0: for i in range(7,6+dat_len): # REMOVE ANY DOUBLE x07 IN DATA-PART !!! if data[i] == '07' and data[i+1] == '07': del data[i+1] ## remove the duplicate # CHECK rest of message: correct command, correct checksum ...?? return data =========================================== The other issue is really simple, replacing two lines of code in the get_fan_status() function. Best regards, Dick

BTW: I just realize that debug_data() won’t work for malformed messages or for just ACK (index out of range)….
