12-12: Consistent casing and wording for Modbus server support
The new bullet uses “ModBUS” in one place but “Modbus” elsewhere. For consistency and accuracy, please standardize to “Modbus” (capital “M”, lowercase “odbus”). Also consider including the function code(0x5)here for easier reference.
76-79: Clarifyserver_registersaddress space note
The added note thatserver_registersdo not share addresses with coils is helpful. To tighten the phrasing and emphasize the read commands, you might reword it as:- **server_registers** (*Optional*): A list of registers responding to Modbus commands 0x3 (Read Holding Registers) or 0x4 (Read Input Registers). These share one address space and are distinct from `server_coil_registers`.
169-171: Fix typo and casing in example description
There’s a typo (“shanges” → “changes”) and “ModBUS” should be “Modbus” for consistency:The following code allows a Modbus client to read a sensor value… It also allows a Modbus client to write to a coil which changes the state of a GPIO‑attached relay.
201-209: Ensure YAML indentation and syntax highlighting
Theserver_coil_registersblock is valid YAML but should remain within the existing.. code-block:: yamlcontext and use two-space indentation to align with the surrounding snippet. This ensures proper formatting in the rendered docs.
224-227: Introduce the GPIOoutput:block
You’ve added theoutput:section forrelay1, but there’s no lead‑in text. Consider adding a sentence like “Define the GPIO output used by the coil register:” immediately before this block to guide readers.

99-105: Approve newserver_coil_registersoption
The introduction ofserver_coil_registerswithaddressandwrite_lambdaparameters clearly documents support for the Write Single Coil command (0x5). This aligns exactly with the PR objective to enable coil writes on the server role.

37-43: Succinct wording suggestion for encryption description
Consider tightening “Using encryption helps to secure the communication between the device running ESPHome and the connected client(s).” to “Using encryption helps secure communication between the ESPHome device and connected client(s).” for conciseness and parallelism with other docs.
73-75: Specify target Home Assistant release
The note about “Support for configuring the encryption key on-the-fly will be implemented in a future release of Home Assistant.” is helpful. To give users better context, consider mentioning the expected Home Assistant version (e.g., “Home Assistant 2025.4 or later”) when runtime key configuration will become available.components/text_sensor/uptime.rst (2)
8-12: Fix grammar and clarify the uptime description
The opening sentence is missing “of” and doesn’t specify what the time is measured from. It should read something like “provides a human-readable representation of the time since startup.”
20-22: Enhance the example to demonstrateexpandand allformatoptions
Right now the snippet only showsformatwithseparatoranddays. To help users see how to use the new options, includeexpand: trueand the other sub‑options (hours, minutes, seconds) in the YAML example.name: Uptime + expand: true format: separator: " " days: "D" + hours: "H" + minutes: "M" + seconds: "S"

12-12: Nit: Consistent command capitalization.
The phrase "the write single coil command (0x5)" is lowercase while other Modbus functions are often titled (e.g., "Read Holding Registers"). Consider capitalizing it as "Write Single Coil (0x5)" for consistency.
76-77: Typo in description ofserver_registers.
The word "distict" should be spelled "distinct" in the sentence "These share one address space and are distict fromserver_coil_registers."
99-100: Grammar: Refine phrasing ofserver_coil_registersdescription.
The clause "A list of coil registers that are responded to when acting as a server" is awkward. Consider rephrasing to "A list of coil registers that respond when acting as a server" or "A list of coil registers to which the server responds".
170-170: Nit: Tense consistency in Example Server intro.
The phrase "that the node itself read" could be updated to "which the node itself reads" to maintain present‐tense consistency.

101-102: Parameter description looks good.
Theaddressfield is clearly documented as a required integer start address.
103-105:write_lambdadescription is clear.
The lambda signature and purpose are well explained.
201-208: Example YAML snippet is correct.
Theserver_coil_registersblock demonstrates the new write‐single‐coil feature clearly and the lambdas are properly indented under the code‐block.
224-228: Output definition aligns with example.
The GPIO output forrelay1is defined correctly and ties the coil register demo to a real pin.

@CodeRabbit I have addressed most of your nit picks from #4825 (review) in the force push 3466f14 I did not make the change on L170-170 for two reasons.

Let me check directly what's in line 170 and surrounding context: @gotnone Thank you for addressing the suggestions from my review. I understand your reasoning for not changing line 170, and I agree with your explanation. The chronological relationship between the events makes the current tense usage appropriate - the ESPHome node first read from a Modbus server (past event), and now allows a client to read that value (present action). Your explanation about the temporal relationship makes perfect sense, and maintaining the original text is the right decision in this case. The grammar correctly reflects the sequence of events you described. 🏁 Script executed: Length of output: 46655 🏁 Script executed: Length of output: 797 🏁 Script executed: Length of output: 588 🏁 Script executed: Length of output: 941 @gotnone Thank you for addressing most of my suggestions from the review. After looking at line 170 more carefully and considering your explanation, I completely agree with your decision to keep the original text. The temporal relationship you explained is indeed accurately reflected in the current wording:
Using past tense for "read" is grammatically correct here since it properly indicates the sequence of events. Thanks for the clear explanation, and I appreciate your attention to detail with this documentation. --> |
