Recently, I embarked on integrating a Shelly Plus H&T sensor into my Home Assistant setup, aiming to monitor temperature and humidity in my living room. The journey, though initially frustrating, turned out to be a rewarding learning experience.
The Setup and Initial Success
I started by installing Home Assistant on a virtual machine running on Windows 10, using the latest stable versions of Home Assistant OS and Core. The Shelly Plus H&T sensor was one of several devices I purchased, including Tapo plugs and Shelly mini G3 relays. To my delight, the sensor initially communicated temperature and humidity data to Home Assistant seamlessly.
The Hiccups Begin
However, my joy was short-lived. After configuring DuckDNS and DNSMasq to expose Home Assistant to the internet, the Shelly integration stopped working. The sensor, while functional with the Shelly app on my smartphone, failed to show up in Home Assistant. Despite numerous attempts to adjust settings, including modifying the WebSocket server configuration and tweaking MQTT settings, the issue persisted.
The Debugging Journey
I spent countless hours poring over forums and documentation, experimenting with different configurations. I even installed an MQTT broker and explored RPC over UDP, hoping to find a workaround. Each attempt brought a glimmer of hope, but the sensor stubbornly refused to integrate.
The Turning Point
Determined not to be defeated, I revisited the basics. I ensured that the sensor was correctly paired and that all dependencies were up-to-date. I also reached out to the community for advice, sharing my debug logs and configuration files. The response was overwhelming—experienced users offered insights and potential solutions, reigniting my hope.
The Resolution
After several days of relentless troubleshooting, I discovered that the issue stemmed from a misconfiguration in the Shelly integration settings within Home Assistant. Correcting this allowed the sensor to reconnect, and now it reliably provides temperature and humidity data, which I’ve successfully incorporated into my automations.
Lessons Learned
This experience taught me the importance of meticulous configuration and the value of community support. It also underscored the need for patience and persistence when dealing with technical challenges. I’m now more confident in troubleshooting future issues and excited to expand my Home Assistant setup further.
