Question 51:
You are operating the IoT infrastructure of a chemical plant where devices are used to ensure that critical valves built in outdoor pipelines are free from frost, even in extreme conditions. In normal weather, the devices operate as planned, but in unexpectedly and extremely cold conditions, the extra heater of certain valves must be turned on remotely. In such cases, you want to have the device report temperature data more frequently, in every minute. You decide updating the device twin as follows:
<pre class="brush:java;">"desired": {
"heaterTemperature": {
"sendFrequency": "1m"
},
...
},
</pre>
Is that the solution you should choose?
