What about Apps that are there already? I caused the last one to crash, was it 14. when updating packages via a terminal emulator on F-Droid and in froze whilst Mosquito was being updated. Obviously it is already there will there be access to it in the Apps section? Also, can I run a terminal emulator and update packages in 4.2? My original plan had been to add Node Red and Mosquito. I may try the Node Red part again or maybe a different MQTT broker. ---

> [@eerke](#): > > maybe a different MQTT broker Why do you need it when there is one already on board? MQTT is a protocol, and a broker is simply an MQTT server. If the NSPanel Pro provides configuration for the port, IP address, login/password, and users (and it does), then any MQTT client (Home Assistant, Node‑RED, OpenHAB, Domoticz, ESPHome, Tasmota, Zigbee2MQTT, any script) can connect to it. The broker is simple, but it works with any MQTT client. ---

I think it would be useful if NSPanel Pro MQTT published the Player topic and Display topic 🤔 ---

> To turn on and off the screen and control the brightness of the screen. `v4.3.0` will support this feature (through Home Assistant’s MQTT Discovery protocol), please bear with us and wait for approximately three weeks. If you are a developer, you can also use NSPanel Pro’s Open API to toggle the display and adjust the brightness. ---

Hello Sonoff Team Since updating my NS-Panels Pro 120, the Sonoff S-Mates only work if I wake the screen first. The latest update available to me is version 4.1.5. Version 4.2 briefly appeared and even started downloading, but then aborted, and now it always says the firmware is up to date. Is this a known bug with the S-Mate? And why can’t I update to 4.2 or 4.2.2? Regards, Paul ---

This is as an MQTT client not a broker. You already have Mosquito installed (as I found out when it crashed when I asked it to update packages): you could let us set a username/password/port a bit like you already do on the iHost. ---

Hello! Have you successfully upgraded now? Regarding the issue with S-Mate not working, could you please share the NSPanel Pro logs right after the problem occurs and send me your device ID separately? I will look into it as soon as possible. ---

Hello, has anyone noticed that after the latest updates of the nspanel pro and the eWeLink app there are anomalies with the TRVZB? In particular, the boost mode is activated without request. ![IMG_2262](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/9/9617d25d1bbca877ae6011bee364b2cbea031d7b.jpeg) ![IMG_2260](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/1/10a7bd4ac75433410f627072bd80c7a54c6dd819.png) The images show the history of two valves present in my house. ---

Hello, unfortunately I am not able to update my NS Panel Pro. I have it on 2.1.0. The update is showing as finished at 125%? I have sent the logs.

Actually, there isn’t really a problem in that sense. And it probably won’t show up in the logs either. S-Mate only works when I click on the NS panel to wake it up. When the panel is in sleep mode, S-Mate isn’t detected. This was possible with the previous firmware. And no, the firmware can’t be updated on either panel. It still shows version 4.1.5 as the latest firmware. I sent the panel IDs via PM. Regards, Paul ---

Hi, I’ve checked the logs, and because the current device is on version 2.1.0, there is a potential issue that could cause OTA updates to fail. Could you please reset this device to factory settings (this will erase the currently bound eWeLink data)? Once the device restarts, please wait 5 minutes to see if the new version downloads normally. If the issue persists, kindly submit the logs and feel free to contact me anytime. ---

@pvshs @kayoot The issue you’re experiencing is likely due to not receiving the update prompt for version 4.2.2. This is because 4.2.2 is still in the testing phase and hasn’t been fully released yet. If you’d like to try it, you can join the beta program using the beta testing tool. Please feel free to reach out if you have any questions or issues. ## 📝 How to Apply Follow these steps to join the Beta Test program: 1. Visit the tool page: [NSPanel Pro Beta Testing Program](https://panel.sonoff.tech/nspanel-pro/beta-test/#/login) 2. Log in using your eWeLink account. 3. Select the NSPanel Pro device you wish to register. 4. Read and accept the risk notice, then submit your application. 5. Wait approximately _5 minutes_, then go to your device’s `Settings -> About -> Software Update` to check for the latest firmware and install it. ---
