I’m building a temp sensor for each room with an esp8266 & a DS18B20 temp sensor. I was able to build the first one without any trouble using esphome and it was discovered by HA. When I built the second sensor, I followed the same process and its showing in esphome but HA won’t recognize it.
I can fetch logs from the first sensor via WiFi and it displays the expected temps. I can also fetch logs from the second sensor via USB (its still connected to the computer Pi4 for debugging) and it displays the expected temps.
The second sensor isn’t recognized by HA and I can’t add it to the esp home integration - its shows an error:
Can’t connect to ESP. Please make sure your YAML file contains an ‘api:’ line.
I’ve tried with both the mDNS entry and well as the IP. Neither works but I can ping both from my MacBook so I know the sensor is on WiFi.
When I gather logs from the second sensor via WiFi I get an error:
