ds18b20 not recognized

[fragolinux]

Operating environment/Installation (Hass.io/Docker/pip/etc.): esphome 1.11.2 as addon in hass.io on ubuntu 18.04, HA 0.89.1

ESP (ESP32/ESP8266, Board/Sonoff): it's a witty board (it has integrated rgb led and 1 button and 1 ldr), i selected esp01_1m as board

Affected component: ds18b20 dallas temperature sensor

Description of problem: it cannot detect any sensor ("[20:51:20][W][sensor.dallas:084]: Found no sensors!"), while on tasmota with "sensors" build it works without any issue... oh, even static ip does not work, i commented it out, on reboot it was still on previous dhcp address (different from the static one, which is out of the dhcp range)

Additional information and things you've tried: as said, in tasmota it just works, on same pin (gpio16), i come from there and this is my 1st esphomized device...
