All sensors eventually connected. Three sensors initally failed to register but addition button presses during registration eventually worked. Freezer applications may stress specifications although some sensors did work. Battery life is still questionable but increasing reporting interval may help. Not thrilled with these but they are a good value and work as advertised with a little persistence.

nothing else like this in the market, great build quality and well though out design to make install seamless. I brought 2 but now I want to replace all of my light switches with these beauties.

Excellent product

Works fine. I like it.

Great little device for the situation where full power circuit is not available at the light switch.
Had a little trouble with flashing Tasmota but solved it by not using sonoff supplied application.

The thermostat now has only one flaw that if you switch to manual setting it will not switch back to automatic at the next timer that most thermostats know.

I ordered two of these, flashed one as a router and kept the other as the coordinator. It appeared to already have the latest firmware. As I previously had a CC2531 configured on my home assistant, it was just a matter of unplugging the old dongle, changing the configuration port to /dev/ttyUSB0 and plugging in the new one. The signal link quality across the entire network has improved. No more laggy behaviours or missing temperature reading. Have 30+ devices on the network. This week I put the second one as a repeater to make the signal stronger and the mesh more resilient. So far so good

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
