~ Tasmota for custom ESP32 smart home devices

In my house, I have a few smart home features: to control ventilation, to open and close solar screens, and to switch a few smart sockets. Up until a couple of days ago, the ventilation and screen controllers operated using custom software running on an ESP32. However, configuring, maintaining, upgrading, and integrating with this custom software gradually became a headache.

Recently, I switched from custom software to Tasmota, an open-source smart home platform targeting ESP32 devices. Tasmota includes a web UI, flexible configuration options, OTA upgrades, and scripting features. The scripting functionality allows devices to be extended with additional commands, which is especially practical for controlling my solar screens. These screens use pulses to toggle between up-stop-down-stop states. By default, Tasmota only supports enabling or disabling a relay, not enabling it for a very brief period (e.g., 150 milliseconds). With a short ‘Berry’ script, such functionality is quickly added.

I appreciate the effort of the Tasmota team to lower the entry barrier for users. They provide ample documentation and a web installer, making setup straightforward. Simply connect your ESP32 via USB, flash it with Tasmota, and configure it—all from your browser. It’s a surprisingly simple process compared to installing a dedicated toolchain. While this might not be what Tim Berners-Lee envisioned 35 years ago, it certainly simplifies the user experience. Lowering the entry barrier even further, some manufacturers even offer smart home devices with Tasmota preinstalled, such as the Nous A1 smart sockets. Eternal september is here.

If you’re managing custom ESP32 smart home devices, consider switching to Tasmota. Its robust features, ease of setup, and active community support make it an excellent choice for both beginners and advanced users.
