Hello everyone! Gladys Assistant **5.3.2** is out! It’s a small release, but it brings the first results of our Zigbee2mqtt audit, a new device category and a few fixes. **Highlights:** - 🐝 **Zigbee2mqtt recognizes your dongle** : Gladys selects the port and model for you - 🚥 **Zigbee2mqtt status you can trust** : Gladys shows Zigbee2mqtt as running only once it really answers, and tells you why when it doesn’t - 💧 **New “Flow sensor” category** , with m³/h and m³/s units - 🚚 **Moving to a new machine** : external integrations now restart by themselves after a Gladys Plus backup is restored - 🔧 **MQTT** : empty payloads are no longer saved as `0` * * * ### 🐝 Zigbee2mqtt: the first results of our audit Zigbee is one of the most used integrations in Gladys, so with @cicoub13 we took a close look at the whole Zigbee2mqtt experience: installing it, choosing the dongle, knowing whether it works, understanding what went wrong when it doesn’t… The first results ship in this release, and it’s only the beginning: **we have a lot more planned** to make the Zigbee integration in Gladys **as simple as possible** , from plugging in the dongle to pairing your first device. **1. Gladys recognizes your dongle** - The setup page now lists ports by the name of the device plugged into them, like `SONOFF Zigbee 3.0 USB Dongle Plus (/dev/ttyUSB0)`, instead of a list of cryptic serial ports. The machine’s own serial ports are hidden behind a link. - When a single known dongle is plugged in, **its port and model are selected automatically**. Gladys can even tell a SONOFF ZBDongle-E from a ZBDongle-P, even though both have the same USB IDs. - New models in the list: **SONOFF Dongle Lite MG21** , **SONOFF Dongle Plus CC2674P10 (Dongle-PP10)** and **SMLIGHT SLZB-06p10**. - In USB mode, you now have to choose a model. Before, leaving it empty quietly used the `zstack` adapter, so a ZBDongle-E never started. ℹ **Existing installations:** nothing changes until you save your Zigbee2mqtt configuration again. If your configuration has no model, Gladys suggests the one it recognized. It is only saved when you click save. **2. A Zigbee2mqtt status you can trust** - Before, Zigbee2mqtt was shown as running as soon as its container started. It could be crashing in a loop (wrong driver, old firmware, unplugged dongle) and still look fine, while the “permit join” switch stayed greyed out with no explanation. - Now Gladys shows Zigbee2mqtt as online only once it **answers a health check**. - On the discover and device pages, a **“Zigbee2mqtt is not responding”** banner shows the container error when Gladys knows it. If Gladys can’t reach the MQTT broker, the banner says so and shows the MQTT error. - On the setup page, a sentence tells you whether Zigbee2mqtt is starting, failing to start or not answering. ⚠ **If you run your own Zigbee2mqtt** (not the one Gladys installs), the health check needs **Zigbee2mqtt 1.21 or later**. The Zigbee2mqtt installed by Gladys is 2.14.2. Big thanks to @cicoub13 for this work, tested on a Raspberry Pi 4 with a SONOFF ZBDongle-P! 🙏 If you have another dongle (ZBDongle-E, SMLIGHT, Dongle Lite…), please tell us in this topic whether Gladys recognized it. Your feedback will help us with the next steps! * * * ### 💧 New “Flow sensor” category Following [this request](https://community.gladysassistant.com/t/ajouter-l-unite-m-s-metre-cube-par-seconde-pour-le-debit-des-cours-d-eau/11463), Gladys has a new **Flow sensor** category, with **m³/h** and **m³/s** units. It covers: - river monitoring stations (Hub’Eau, Vigicrues…), which report flow in m³/s - pipe flow meters and pumps It can be used with MQTT and external integrations. Zigbee2mqtt now understands the m³/s unit, and the AI assistant can read flow values. Thanks @Will_71! 🙏 * * * ### 🚚 Moving Gladys to a new machine Following [this topic](https://community.gladysassistant.com/t/changer-dinstance/11483): when you restored a Gladys Plus backup on a new machine, external integrations failed to start because their Docker images weren’t on the new machine. You had to uninstall and reinstall each one. Now Gladys **downloads the missing images in the background** at startup, and the integrations start once the download is done. Zigbee, MQTT and your scenes don’t wait for the download, and the integration shows as “loading” until it’s ready. * * * ### 🔧 Other fixes - **MQTT** : an empty payload, a `null` value or a missing JSON path on a custom topic is now ignored. Before, it was saved as `0`, so a temperature could suddenly read 0 °C. Thanks to [huangkongsheng](https://github.com/huangkongsheng) for this contribution! - **Security** : dependency update (axios) in the (deprecated) OpenWeather integration. * * * **Updating:** if you use Watchtower, Gladys updates itself within 24 hours. Otherwise, you can update in one click from the settings. Share your feedback here! 🙂
