Having the same issue. INPUT mode is working though

ddean6232 commented 5 years ago

Have not tested inputs. Need output.

puerari commented 5 years ago

I'm having the same issue with OUTPUT. I have not tested inputs because my project is on a PCB.

redstar2k1 commented 5 years ago

I'm also having problems with OUTPUT mode.

puerari commented 5 years ago

I did a pull request with the solution to the problem. Waiting for analyse.

redstar2k1 commented 5 years ago

@puerari I've tested your diff and it works for me. Great job.

ddean6232 commented 5 years ago

No sure how I can test. Knowledge limited.

Hi I also have the same problem OUTPUT does not want to work with esp8266 d1_mini while for INPUTs it works cm of can solve

Questo è il codice:

esphome: name: esp_realy_8ch platform: ESP8266 board: d1_mini

wifi: ssid: "my SSID" password: "my password" manual_ip: static_ip: my ip subnet: 255.255.255.0 gateway: my gateway
