Hi again,
I did not find a link in the instructions anywhere. Where exactly is the alarm set, would you help me ?! In fact, I need to send printh 0xXX 0xXX 0xXX 0xXX (4 bytes HEX) at a specific time to the Arduino via serial port while in sleep mode.
Thanks!

Worked straight out of the Box. Sensitive radio. Best value for money. I wished it only had a second input for VHF antenna to conveniently operate on HAM bands w/o frequently changing the antennas on the delicate SMA connector. Otherwise very satisfied overall.

I like Nextion HMIs very much. They are inexpensive and easy to use.

I have worked with the 2.4" Basic Series model, the 4.3" Intelligent Series model, and now the Discovery Series HMI built into the Sonoff NSPanel. I like that a consistent design has been used on the different sizes and series. I plan to use this brand of HMI in many of my future projects.

As for the '4.3" Nextion Intelligent Series HMI Touch Display with enclosure' specifically, I bought this unit expressly for two reasons: 1. Having the HMI already installed in an enclosure makes it easy to deploy (i.e. mount on a wall) without having to buy or 3D-print a suitable enclosure. 2. The Intelligent Series is capable of sound output (e.g. WAV files) via a speaker (which is built into the enclosure). Both of these features were selling points for me.

After finding out that the pre-existing wiring that I was using to communicate with the HMI was causing data corruption, I decided to build a "wireless" HMI using an ESP8266 (Wemos D1 Mini). Luckily, the HMI enclosure was easily openable, and there was enough empty space inside that I was able to mount the D1 Mini board on the back panel of the enclosure and then connect the HMI's power and data lines to the D1 Mini. After a little bit of extra programming effort, the improvised device was working very well, and I have decided to use this design for all of the HMIs in my establishment. I love it that I was able to retrofit an IoT microcontroller into this device. (And, after all of that work, I discovered the new Sonoff NSPanel, which is essentially a more professional version of this, with an ESP32 microcontroller driving a Nextion HMI as a wall-mounted IoT control panel.)

If I have anything negative to say about this particular unit, I find that the included mounting brackets and enclosure mountpoints are klunky and cumbersome. I wanted to mount the HMI on a wall, and was unable to do so without creating a 3D-printed mounting plate. In future, I would hope to see more / better mounting options for this model.

All in all, I think these HMIs are wonderful, and it has been a pleasure to use them in my automation projects.

Fast delivery. Upconverter works very well with Airspy R2 to provide HF frequency reception.

Prodotto davvero fantastico, fa il suo dovere, unica pecca non poter vedere i consumi graficamente sia mensili che settimanali.

got several of those devices and they work great! flashed with tasmota ofc

did firmware update (via terminal) and works with mqtt2zigbee

If you are looking to replace your hard drive in your Instant Replay by 360 systems this is the item for you. There is a tutorial on YouTube that if you follow the programming down to the letter you can resurrect your instant reply too

Very good

Plugged the dongle and USB-extension cable to my VMware host, did USB-passthrough to virtual machine and start Zigbee2MQTT Docker container. So far everything just works, as they should. Can finally change my home automation away from the previous proprietary setup.

Allo je commence à peine à utiliser mon HMI ça fonctionne très très mais une chance qu'il y a YouTube pour les tutos car ce n'est pas facile niveau débutant. Évidemment, je recommande fortement ce produit car l'éditeur est très intéressant mais comme je disais ce n'est pas facile de s'approprier tout ça.. je vais en racheter pour d'autres projets car j'adore les produits N'étions à vous d'en juger..

I live 500 metres from a 50 kW MW and 20 km from multiple 250 kW FM transmitters, and this sdr handles MF and HF way more cleanly than my portable radios.

an industrial equipment with lan connection... excellent quality and it works perfectly.

It's basically a drop in replacement for the Sonoff Basic but with zigged support, Pairing with ZHA was easy and without trouble, I will be replacing all my wifi smart switches with zigbee whenever I can.

Worked out of the box with zigbee2mqtt and homeassistant. Due to the good documentation i was able to flash ist with the latest firmware to be 100% compatible to more vedors.
