by Luna Greco 77 views

Hey guys! Today, we're diving into a common challenge faced by smart home enthusiasts: integrating the Petwant 6 Meal Smart Feeder F13-W with Tuya Local. This guide will address a specific user's request for support, but it's packed with insights that can help anyone tackling similar smart device integrations. Let's break it down and get your pet feeder working seamlessly within your local network.

Understanding the Initial Problem

Our user, let's call him Alex, ran into a snag while trying to set up his Petwant F13-W feeder with Tuya Local. After adding the device, he noticed that all the buttons displayed an "unknown status," and the battery level was stuck at a dismal 1%. This is a frustrating situation, but not uncommon when dealing with smart home integrations. It often boils down to compatibility issues or misconfigured device parameters. Alex helpfully provided the log messages, product ID, DPS (Data Point Selectors) information, and even the user manual – awesome! This level of detail is super helpful for troubleshooting.

Analyzing the Log Message

Let's start by dissecting the log message. The critical part reads:

Device matches nedis_zbrc10wt_remotecontrol with quality of 17%. DPS: {"updated_at": 1754122683.9996603, "3": 1, "4": "done", "108": "", "112": "{\"value\":1,\"time\":1754142800,\"type\":1}", "113": 0, "130": "36.4.10"}

This tells us a few things:

  1. The device is being misidentified: Tuya Local is matching the Petwant feeder with a nedis_zbrc10wt_remotecontrol, which is clearly incorrect. This mismatch is likely the root cause of the "unknown status" issue.
  2. Low match quality: The "quality of 17%" indicates a poor match, further supporting the misidentification theory.
  3. DPS data: The DPS data provides a snapshot of the device's current state. While it's not immediately clear what each DPS represents without proper configuration, it's valuable information for creating a device profile.

Examining the Product Information

Alex also shared the Product ID (vuizkgeyohvpcrmr) and detailed DPS information. This is gold! The DPS information is a structured breakdown of the device's functionalities and how they are controlled. Let's look at some key DPS points:

  • DPS 3 (manual_feed): This is a read-write value (0 or 1) for triggering manual feeding. This is a crucial function that needs to be properly mapped.
  • DPS 4 (feed_state): This is a read-only enum indicating the current feeding state (standby, feeding, done). Monitoring this state is essential for feedback and automation.
  • DPS 10 (battery_percentage): This read-only value represents the battery level (0-5000). The user reported a 1% reading, which might be a misinterpretation due to incorrect scaling. We'll need to address this.
  • DPS 101 (meal_plan_num): This read-write value determines the maximum number of meal plans (1-5). This is important for scheduling feedings.
  • DPS 108 (meal_plan2): This read-write string likely stores the actual meal plan data. Understanding its format is key to setting up schedules.
  • DPS 112 (feed_record): This read-only string provides a log of feeding events, including the amount, time, and type (manual or scheduled).
  • DPS 113 (vip_alarm): This read-only value indicates various alarm states (feeding success, device error, motor jam, etc.). This is important for monitoring device health.
  • DPS 130 (mcu_version): This read-only string provides the firmware version. This can be useful for identifying compatibility issues or available updates.

The Importance of DPS Mapping

The core challenge here is mapping the DPS values to their corresponding functions within Tuya Local. Without this mapping, Tuya Local can't correctly interpret the device's status or send commands. This is why the buttons show "unknown status," and the battery level is likely misreported. Properly mapping the DPS points will unlock the full potential of the Petwant feeder within your smart home setup.

Steps to Resolve the Integration Issue

Okay, so how do we fix this? Here’s a step-by-step approach, blending technical troubleshooting with a user-friendly tone.

  1. Create a Custom Device Profile: The first and most crucial step is to create a custom device profile in Tuya Local for the Petwant F13-W. Since the device is being misidentified, we need to tell Tuya Local exactly what this device is and how it functions. This involves manually configuring the DPS mappings.

    • Dive into the Configuration Files: You'll likely need to edit the Tuya Local configuration files (usually YAML files) to define the new device profile. This might sound daunting, but it's just a matter of adding the correct entries with the right DPS information.
    • Specify the Device Type: Within the profile, you'll need to specify the device type (e.g., pet_feeder) and the Product ID (vuizkgeyohvpcrmr). This is how Tuya Local will identify the device correctly.
    • Map the DPS Points: This is the heart of the process. For each DPS value (3, 4, 10, 101, etc.), you'll need to define its function (e.g., switch for manual feed, select for feed state, sensor for battery level) and any relevant attributes (e.g., min, max, unit for battery level). This tells Tuya Local how to interpret and control each aspect of the device.

  2. Utilize the DPS Information: Remember that treasure trove of DPS information Alex provided? We'll use that to meticulously map each DPS point in the custom profile. For example:

    • DPS 3 (manual_feed): Configure this as a switch entity. When the switch is turned on (value 1), the feeder should dispense food manually. When it's off (value 0), it should be idle.
    • DPS 4 (feed_state): Configure this as a select entity with options for standby, feeding, and done. This will allow you to monitor the feeder's current state in your smart home dashboard.
    • DPS 10 (battery_percentage): Configure this as a sensor entity with a range of 0-5000. You might need to apply a scaling factor (divide by 100 or 1000) to get a percentage representation. Also, ensure the unit_of_measurement is set to %.
    • DPS 108 (meal_plan2): This is the trickiest one. You'll need to understand the string format used to store meal plan data. This might involve some trial and error or consulting with other users who have integrated similar devices. Once you understand the format, you can create automations to set and modify meal plans.

  3. Address the Battery Level Issue: The 1% battery reading is likely a scaling issue. As mentioned above, you might need to divide the raw DPS value (0-5000) by 100 or 1000 to get a percentage. Adjust the scale or multiplier attribute in your custom profile to correct this.

  4. Test and Refine: After creating the custom profile and mapping the DPS points, it's time to test! Try manually feeding, setting up a meal plan, and monitoring the battery level and feed state. If something isn't working as expected, go back to the profile and adjust the mappings. This is an iterative process, so don't be discouraged if it takes a few tries to get everything dialed in.

  5. Leverage Community Support: The smart home community is awesome! If you're stuck, reach out to forums, online groups, or the Tuya Local project's issue tracker. There's a good chance someone else has integrated a similar device and can offer guidance.

Additional Tips for Tuya Local Integration
