I’d like to share some projects I’ve been working on that provide some nice integration options between SmartThings and other external applications. These use MQTT, which if you’re not familiar with, you can find plenty of information about on the internet. Put simply, you install what’s called an…

Thank you! I had seen that example before – but wasn’t sure how to use it since I had the MQTT publishing “device” installed and didn’t have the temperature device. I get it now, and after hydrating a virtual “mqtt temperature” device, I was able to use the exact rule text to call the setvTemp comm…

The MQTT Devices driver crashes if a numeric value NaN is received via MQTT. My RPi Python program sends the temperature values using MQTT to the ST Hub. From the source of the temperature values became a NaN value and the Python program sent it with the MQTT Retain flag. This caused the dri…

Hi, I got a new router and even though I got my node red (mosquitto broker) running with a new IP address I can’t connect the Smartthings Device Handler to the broker. Does the IP address need to be 192.168.1.xxx? I have 192.168.68.xxx

After a struggle I got it working!

I bought my first Shelly device this week. The device is Shelly 1 Gen3. I wanted to use local communications to ST Hub. I didn’t want add more drivers to the Hub and decided to try MQTT communication. I already had the MQTT Devices driver ready to use. MQTT communication seems to work using MQT…

[image] TapioX: I bought my first Shelly device this week. The device is Shelly 1 Gen3. I wanted to use local communications to ST Hub. I didn’t want add more drivers The Shelly 1 Gen4 has just released and includes Matter and Zigbee support out of the box so no need for anything fancy or …

I’m in no hurry to use Matter. The reliability of the Matter WiFi bulb (I have one Wiz bulb) is clearly worse than that of Zigbee bulbs. The Matter WiFi bulb is offline almost every week. MQTT’s reliability is on the same level as Zigbee.

Got it, Gen4 has Zigbee too in addition to Matter, I guess it’s worth it as first Shelly device to have more options. MQTT if I understand correctly requires not only the SmartThings hub and this custom driver but another machine running 24/7 to run the MQTT broker. I’m surprised with your experie…

I started using a new The Pill by Shelly.

The Pill by Shelly - Shelly Europe

MQTT communication to / from The Pill by Shelly works using MQTT Devices driver.

I tested The Pill’s temperature measurement, output, and input functionality via MQTT.
