Hi, I’m feel I’m extremely close to getting this working but probably having one tiny issue. I’m wanting this steel frame lamp I made to be touch-activated via home assistant (currently plugged into a smart wall plug)
I’ve flashed the ESP32-S2 Mini with what I’m sure is the working code (below), with a 1M ohm resistor coming from GPIO4
esphome:
name: lamptouch
friendly_name: lamptouch
esp32:
board: esp32-s2-saola-1
framework:
type: arduino
esp32_touch:
setup_mode: true
logger:
level: DEBUG
api:
encryption:
key: "redacted"
ota:
platform: esphome
password: "redacted"
wifi:
ssid: !secret wifi_ssid
password: !secret wifi_password
ap:
ssid: "Lamptouch Fallback Hotspot"
password: "redacted"
captive_portal:
binary_sensor:
- platform: esp32_touch
name: "Lamp Touch"
id: LampTouch
pin: GPIO4
threshold: 1000
on_press:
- lambda: |-
int raw = id(LampTouch).get_value();
ESP_LOGD("touch", "Raw value: %d", raw);
- homeassistant.service:
service: switch.toggle
data:
entity_id: switch.lampexample
when opening the logs, I’m seeing the following regardless of whether I touch either side of the resistor or not

I’ve also touched the frame of my macbook while grabbing the wire and no changes thinking it was a grounding issue. Any ideas why I’m not seeing ANY change in capacitance readings while logging? I’ve tried two other pins on the board and same issue.
