Hey everyone, I’ve been diving into the world of wireless sensors lately, and I wanted to share my journey with you all. I’ve been using ESPHome, Node-Red, and Home Assistant to set up a system that displays sensor data directly on my Android phone, kind of like a digital dashboard. It’s been a fascinating project, but also a bit of a learning curve!
So far, I’ve managed to get my ESP8266 D1 mini connected to my phone’s hotspot, and I’ve set up an MQTT broker on my phone using the MQTT Broker App. I also installed RedMobil to handle Node-Red on my phone. The communication between Node-Red and the MQTT broker is working perfectly, but I’m hitting a snag when it comes to getting sensor data from the D1 mini to show up on my phone’s dashboard. It seems like an IP address issue, but I’m not entirely sure how to resolve it.
I’ve tested the setup on my local network, and everything works fine there. The D1 mini sends data to the MQTT broker, and I can see the sensor readings on a dashboard I created. But when I switch to my phone’s hotspot, the D1 mini can’t connect to the broker, even though it’s running on the same network. I’ve tried adjusting the IP addresses and ports, but nothing seems to fix the issue.
I’d love to hear from anyone who has experience setting up a similar system. Any tips or tricks would be incredibly helpful! I’m almost there, and I just need that final push to get everything working smoothly. Thanks in advance for your support!
