Hi @Anonymous,
Could you please share a full screenshot of your flow's configuration?
I agree with @Pieter_Veenstra's thought almost, I have made a test on my side and please take a try with the following workaround:
- Add a proper trigger, here I use Flow Button trigger.
- Add a Compose action, Inputs set to following json data that you mentioned:
[
{
"time": "2018-04-04T00:00:00",
"temperature": 8.7,
"relativeHumidity": 98,
"rainPastHour": 5.3
},
{
"time": "2018-04-05T00:00:00",
"temperature": 8.8,
"relativeHumidity": 98,
"rainPastHour": 5.3
},
{
"time": "2018-04-06T00:00:00",
"temperature": 12,
"relativeHumidity": 98,
"rainPastHour": 5.3
},
{
"time": "2018-04-07T00:00:00",
"temperature": 10,
"relativeHumidity": 98,
"rainPastHour": 5.3
},
{
"time": "2018-04-08T00:00:00",
"temperature": 6.1,
"relativeHumidity": 98,
"rainPastHour": 5.3
}
]
- Add a "Select" action, From set to output of "Compose" action. Within Map entry, type one entry. Name set to Temp and Value set to following formula:
item()?['temperature']
- Add a Variables-> "Initialize variable" action, Name set to MaximunValue, Type set to Float and Value set to following formula:
first(body('Select'))?['Temp']
- Add a Variables-> "Initialize variable" action, Name set to MinimumValue, Type set to Float and Value set to following formula:
first(body('Select'))?['Temp']
- Add a parallel branch action, within left branch, add a "Apply to each" action, Input parameter set to output of "Select" action. Wihtin "Apply to each" action, add a Condition, Click "Edit in advanced mode", type the following formula:
@greater(item()?['Temp'], variables('MaximunValue'))
Within "If/yes" branch of Condition, add a "Set variable" action, Name set to MaximunValue, Value set to following formula:
item()?['Temp']
Within right branch, add a "Apply to each 2" action, Input parameter set to output of "Select" action. Wihtin "Apply to each" action, add a Condition, Click "Edit in advanced mode", type the following formula:
@less(item()?['Temp'], variables('MinimumValue'))
Within "If/yes" branch of Condition, add a "Set variable" action, Name set to MinimumValue, Value set to following formula:
item()?['Temp']
- Under the Parallel branch action, add a Compose action, Inputs set to MaximunValue variable and MinimumValue variable.

The flow works successfullly as below:
