![]() Note that the main PCB is marked with “E32-MSW-NX” and “NSPanel-EU” if you open it.Īnd looks like he is also planning on posting code here:īlakadder wrote: I’ve also successfully decoded most of the NSPanel custom protocol, just need to figure out why the touch function stops working when doing some actions. ![]() NX4832F035 Nextion 3.5″ Discovery Series HMI Touch Display can be purchased as a separate unit directly from ITead for $29.90 (US) if need it for development or want to test it in an ESP32 DIY project:īlakadder (in Tasmota discussions): " With this discovery we confirm it is possible to upload custom GUI created in Nextion Editor."īlakadder has posted updated information on his findings here: Please describe your use case for this integration and alternatives you've tried:įYI, Tasmota developer blakadder now discovered that SONOFF NSPanel uses Nextion Discovery 3.5” NX4832F035 screen type part: ITead has also posted specific IO (Input-Output) definition documention for Sonoff NSPanel in a new Kickstarter campaign update: Nextion HMI Project Upload Protocol specifications: ![]() The information so far is that it does not use the protocol that ESPHome support for Nextion HMI but instead a custom protocol: Especially when taking into consideration that Efuses are not burned and pin headers on the board are easy to use for a solderless flash. The first thing they discovered it that has practically been designed it to be hacked and flashed with third-party firmware. HA-TB303 and blakadder are two that have especially connected a lot of information about the internal workings of these:Īlso, the community at the unofficial Nextion/TJC chat room on Discord have been making some discoveries about its display: There is some interesting discussions on the Home Assistant community forum about hacking it with ESPHome and/or Tasmota: The screen then has serial commands mapped to UI elements and can be sent and received from ESPHome firmware to control it. are created using Nextion Editor software, and then then the project files/assets are uploaded directly into the Nextion screen. It also contains a temperature + humidity sensor and two integrated low-amp relays for 220V/300W or 110V/150W capacity respectively, but the point is really for it to act as remote control of scenes and running widgets (local applications or scripts) such as for example an HVAC thermostat.Īs I understand all Nextion displays as their own integrated microcontroller unit (STM32GO ARM Cortex-M0+ 64MHz Onboard MCU Processor) so that will off-load most of the heavy lifting work and all text and graphics, animations, etc. Looks like a model each for Europe and North America “NSPanel-EU” and “NSPanel-US”. Many tech review bloggers/vloggers who received preview prototype units seem to complain about its lack of integrated motion sensor for presence detection so can automatically turn on the screen backlighting, (and I like to also add the request for its DS18B20 temperature-only sensor to be replaced with a DHT22, AM2301, or Si7021 temperature and humidity combo sensor). It is listed at MSRP $74.90 but early-bird version is currently sold via this Kickstarter campaign for around $54 each or $99 for two:Ī lot of information had already leaked via its FCC certification (FCC ID 2APN5NSPANEL): ![]() Request support in ESPHome for SONOFF NSPanel touchscreen display by ITead = ESP32 based with custom Nextion HMI screen: Describe the problem you have/What new integration you would like ![]()
