{"NAME":"Proscenic T21","GPIO":[0,2272,0,2304,0,0,0,0,0,0,0,0,0,0],"FLAG":0,"BASE":54}

This device uses a Tasmota incompatible module which needs to be replaced with an ESP. Besides the module, this process will require a heat gun, soldering tools and moderate soldering skill.

While not supported with the existing hardware, the Wi-Fi module is contained on a separate board connected to the main PCB with a 4 pin PH2.54 connector. This board can be easily replaced with a NodeMCU or any other 5V powered board or module and wired to the connector using Dupont cables. Once you open it its much easier than having to solder to a Wi-Fi module.

The top lid is held by 4 big plastic clips. Use a thin prying tool to slowly go around until all the 4 clips are loose enough to lif the lid. Unscrew and remove the protective plastic grid to get access to the Wi-Fi module which is screwed in on the front plate.

Connect the pins to the connector following the pinout.

I removed the very annoying buzzer from the relay PCB and replaced it with a DFPlayer MP3 player that triggers on dpId reports with actual sound prompts. Demo on YouTube
