Mask filter

[CPichon2]

Hello, first of all, thanks for your great job, very usefull to manage different UART frames.
just one issue regarding how to apply a mask on a sensor statement coz sometimes only one part of the byte is needed and so far I didn't find any solution with a standard format or lambda format. (not expert), so thanks for your help.

If you could share the actual packet you want to mask, I can show you how to configure it.

[CPichon2]

for instance; byte D4 and mask 0x1F to apply, so that I get the decimal value of 20 (nb of the day) Thanks

If the packet is 0x03, 0x01, 0xD4, it can be configured as follows. Could you please upload your actual YAML?

sensor:
  - platform: uartex
    name: "Temperature"
    state: [0x03, 0x01]
    state_number: |-
      float value = (data[2] & 0x1F);
      return value;

ok it works (once you know the correct syntax , it's fine) above the yaml config

I asked for the YAML just in case, but I'm glad to hear it's working!
