GUITION has a new version of its rotary knob with a built-in round touchscreen. The JC3636F118C-I-YR1 swaps the ESP32-S3 of the earlier JC3636K518C for Espressif's ESP32-S31, which brings Wi-Fi 6 and an 802.15.4 radio for Zigbee and Thread. CNX Software wrote it up on 22 October 2026 after a reader pointed it out, and the knob is already listed on
A Home Assistant dashboard on an e-paper panel usually means rebuilding it in ESPHome's display lambdas or rendering screenshots on a server. ESPHome now has a third route. A new vnc component, written by Petar Petrov and merged into the development branch on 22 October 2026, connects to a VNC server and draws its screen on the device's display. A
Getting a CO2 reading out of a Sensirion SCD41 takes about ten lines of ESPHome YAML. Keeping that reading honest over months is the harder part. The sensor corrects its own drift with an algorithm that makes assumptions about your room, and if the room doesn't meet them, the numbers slowly move away from reality without any error in the logs. Wiri
Espressif's ESP-Mosaico can now be bought from the company's own Mosaico store. The Vision Combo Kit, with the core unit (board revision V1.2), a camera module and an interaction module, costs $59, and a battery module is offered separately for $15, according to CNX Software on 21 October 2026. Until now the kit had mostly turned up on Taobao and t
ESPHome 2026.10.0 went stable on 21 October 2026, after six betas. The project counts 786 merged pull requests from more than 60 contributors. Most of that work is internal, but two changes reach almost every device: firmware updates now travel compressed, and ESP8266 firmware is built by a new toolchain.
Battery-powered ESPHome nodes usually work in bursts: wake up, read a sensor, send the value, go back to deep sleep. A new esp32_ulp component gives them a third option. Merged on 21 October 2026 into the development branch for ESPHome 2026.11, it builds a small C program for the ESP32's low-power coprocessor, embeds it in the firmware and runs it.
A heating automation in Home Assistant, or its Generic Thermostat integration, makes every on/off decision on the server. When Home Assistant restarts for an update, or Wi-Fi between it and the relay drops, nothing is in charge of the heater. ESPHome's thermostat climate platform moves the control loop onto the ESP32 itself. The board reads the tem
Audio on ESPHome devices has mostly meant I2S: an amplifier or DAC board for output and a MEMS microphone for input, wired to the right pins. A new usb_audio component adds another route. An ESP32 with a USB OTG port can act as a USB host for USB Audio Class devices: sound cards, USB DACs, USB microphones and speakerphones. GitHub user ab-tools ope
ESPHome is getting a display platform for reflective monochrome LCDs, screens that use room light instead of a backlight. The new st7305 component drives panels with Sitronix's ST7305 and ST7306 controllers over SPI. Clyde Stubbs (clydebarrow) wrote it and merged it into ESPHome's development branch on 19 October 2026 at 10:57 Polish time, right af
