The micronova component needs some externall electric circuitry. The referenced pages show the minimal circuit without pullup resistor connected to RX (The same schematic is also shown on the ESPHome page). There's no mention about a pullup on the various related partial website. There's only a hard to find zip-archive with full PCB project which shows it. This is easily missed by esphome users. So, i'd like to add a warning. To either activate the internal pullup, or connect an external pullup resistor.

217-224: ⚡ Quick winDemonstrate the pull-up configuration in the example.
The example configuration should demonstrate the recommended Pin Schema configuration for the RX pin pull-up that is now documented in the warning. This ensures users following the example will have the correct setup.

47-49: ⚡ Quick winEnhance the warning with resistor value guidance and clarify which pin.
The warning is helpful and correctly placed. Consider these improvements:
- Specify the pin more clearly: Mention that it's the UART
rx_pinthat needs the pull-up configuration- Add resistor value guidance: When suggesting an external resistor, provide a typical value range (e.g., 4.7kΩ to 10kΩ)
- Reference the example: Point readers to the example configuration section where this should be demonstrated

For the micronova component to work user needs some external electric circuitry.
The esphome-documentation references external websites showing the minimal circuit without pullup resistor connected to RX (The same schematic is also shown on the ESPHome page). There's no mention about a pullup on those various related partial website.
There's only a hard to find zip-archive with PCB project which has a pullup-resistor. This is easily missed by esphome users.
So, i'd like to add a warning. To either activate the internal pullup, or connect an external pullup resistor.
ps. i had a previous pull-request. i accidentally deleted the base repository. This pull request includes previous review result.
