I'm currently working with Home Assistant (HA), Node-RED, and ESPHome. This is my first time using these technologies.
I have a soil moisture sensor that sends data through ESPHome to Home Assistant. HA then sends the humidity percentage to Node-RED, and Node-RED is supposed to send a notification to my phone (via the HA app) when the humidity is above a certain threshold — nothing too fancy.
Everything worked fine last weekend when I was at home. Now I’m at my aunt’s house, and I had to make some changes:
I updated the Wi-Fi SSID and password on my ESPHome board.
I changed the server URLs in my Node-RED nodes.
I switched from my home Wi-Fi to my mobile hotspot.
After these changes:
My Node-RED flow shows as running, but nothing is printed in the debug window.
In Home Assistant, my ESPHome device shows as unavailable, even though the ESPHome logs look fine and it’s connected to the hotspot.
I already tried restarting the Docker containers (which helped the last time), but this time it didn’t work.
Any help or suggestions would be really appreciated!
