Smartwings Blinds: Zwave Position In ZwaveJS2MQTT But Not Home Assistant?

by RICHARD 74 views

Hey everyone, let's dive into a bit of a head-scratcher I've been dealing with: my Smartwings blinds, specifically those using Zwave, are showing their blind position perfectly fine in ZwaveJS2MQTT, but for some reason, that crucial information isn't making its way over to Home Assistant (HAAS). It's like the blinds are sharing their secrets with one friend (ZwaveJS2MQTT), but not with the rest of the crew (Home Assistant)! Let's break down this issue, troubleshoot it, and hopefully, get those blind positions synced up in HAAS. This is a common problem, and understanding the ins and outs can save you a ton of headache.

Understanding the Problem: Zwave, ZwaveJS2MQTT, and HAAS

Before we get our hands dirty, let's get our heads around the technology involved. Zwave is the wireless communication protocol that your Smartwings blinds use to talk to the outside world. Think of it as the language they speak. ZwaveJS2MQTT is a middleman, a translator, or a bridge if you will. It takes the Zwave language from your blinds and converts it into a language that Home Assistant understands (MQTT). Home Assistant (HAAS) is the brains of the operation, the central hub where you control all your smart home devices, including your blinds. The blind position is, quite simply, how open or closed your blinds are, usually expressed as a percentage (0% closed, 100% open). The heart of this issue is a disconnect in the data transfer from the blinds, through ZwaveJS2MQTT, and into Home Assistant. The core issue is that the information about the blind position gets lost in translation or isn't being correctly interpreted by HAAS. When things are working as they should, HAAS displays this blind position, and you can control your blinds smoothly from your HAAS interface. When the data isn't flowing correctly, however, you are left with blinds that function, but without knowing their current position, which limits their usefulness.

Possible Causes of the Issue

There are several reasons why your blind position might not be showing up in Home Assistant, even though it's visible in ZwaveJS2MQTT. Here's a breakdown of some of the most common culprits:

  • Incorrect Configuration in ZwaveJS2MQTT: This is often the root of the problem. You might have misconfigured the device in ZwaveJS2MQTT, and therefore, it’s not publishing the blind position data correctly. This could involve incorrect settings for the device's node information or how the position attribute is being reported. Double-check that the device is set up to report its position and that the configuration correctly reflects your Smartwings blinds' specific requirements.
  • MQTT Topic Configuration: ZwaveJS2MQTT uses MQTT topics to send data to Home Assistant. If the MQTT topics aren't configured correctly, or if Home Assistant isn't subscribing to the right topics, it won't receive the blind position updates. Ensure that the topics in ZwaveJS2MQTT match the topics HAAS is set up to listen to. This involves making sure the topic names, payloads, and other MQTT settings are accurate and aligned with your HAAS MQTT integration.
  • Home Assistant Entity Setup: Even if ZwaveJS2MQTT is sending the data correctly, Home Assistant might not be set up to recognize it. This often involves creating or correctly configuring the entity for the blinds in HAAS. Check the entity's settings in HAAS and make sure it's configured as a cover entity (as it should be for blinds) and that it's receiving the correct attributes from MQTT. Often, incorrect entity settings can cause the position data to be ignored by HAAS.
  • Firmware or Compatibility Issues: Although less common, outdated firmware on either your Zwave devices or ZwaveJS2MQTT can sometimes cause compatibility problems. Ensure that your Smartwings blinds and ZwaveJS2MQTT are running the latest firmware versions. This may resolve any bugs or issues that might be preventing the correct data transfer. Checking the compatibility of your devices and software is a crucial step.
  • Network Issues: Zwave and MQTT rely on a solid network connection. If there are network problems, data packets might be lost or delayed, preventing HAAS from receiving updates. Check your network's stability and ensure there are no major connectivity issues between your Zwave devices, ZwaveJS2MQTT, and Home Assistant. Addressing network issues first can eliminate a common source of problems. A weak Zwave signal can be equally problematic.

Step-by-Step Troubleshooting Guide

Alright, let's get practical. Here’s a step-by-step guide to troubleshoot this issue, covering the main areas where problems usually arise. Grab your coffee, and let’s get started.

1. Verify ZwaveJS2MQTT Configuration

  • Access the ZwaveJS2MQTT UI: Log in to your ZwaveJS2MQTT interface. You should be able to access this via your web browser. You'll usually find this through the IP address and port you assigned when installing ZwaveJS2MQTT.
  • Check the Device Details: Navigate to the device details for your Smartwings blinds. Look for the
