Problems with custom Template to monitor harddisc temperature

Help
1

Hi,
i’d wrote a alert for Harddisc Temperature, but Harddisc and temperature are not showing in template. Alert will come up if temperate exceeds 55 degrees.

Alert Rule - SQL Statement
SELECT * FROM devices,applications,application_metrics WHERE (devices.device_id = ? AND devices.device_id = applications.device_id AND applications.app_id = application_metrics.app_id) AND application_metrics.value > 55 AND (application_metrics.metric LIKE ‘%_id190’ OR application_metrics.metric LIKE ‘%_id194’)

Template Code:
{{ $alert->title }}

Device Name: {{ $alert->hostname }}
Severity: {{ $alert->severity }} 
Timestamp: {{ $alert->timestamp }}
Uptime: {{ $alert->uptime_short }}
@if ($alert->state == 0) Time elapsed: {{ $alert->elapsed }} @endif
Location: {{ $alert->location }}
@foreach ($alert->$faults as $key => $value)
#{{ $key }}:
Serial Number: {{ $value['metric'] }}
Temperature: {{ $value['value'] }} °C
Previous Temperature: {{ $value['value_prev'] }} °C
@endforeach

i found it myself " ° " seems to be the problem:
for others who like to use such a template also,
my running Harddisc temperature warning template now looks like:

Device Name: {{ $alert->hostname }}
Severity: {{ $alert->severity }} 
Uptime: {{ $alert->uptime_short }}
@if ($alert->state == 0) Time elapsed: {{ $alert->elapsed }} @endif
Timestamp: {{ $alert->timestamp }}
Location: {{ $alert->location }}
@if ($alert->description !="")Description: {{ $alert->description }} @endif
@if ($alert->notes !="")Notes: {{ $alert->notes }} @endif

@foreach ($alert->faults as $key => $value)
Serial Number: {{ $value['metric'] }}
Temperature Celsius: {{ $value['value'] }}
@endforeach
