Exccellent Thermometer

Purchased this device to have a thermometer at the house with logging functionality. I was able to set it up with my account on the Helium network and get telemetry data sent. While the device can be set to different frequencies as noted in the description - the physical antenna is for 915MHz, so you may need to purchase a different antenna to use it in different region. I have also noticed that the device will send very frequent telemetry events if there is a rapid change in temperature - not sure if this is a feature or a bug. The display is only in celcius (which I prefer) but other users not like this. Also shipping is from China, so the package does take longer to arrive than the other items shipped locally from Robotshop
