Archer c7 v2 temperature sensor

Trying to use Luci statistics with collectd-mod-thermal and collectd-mod-sensor. Starting to wonder if this hardware has a thermal sensor.

/sys/devices/virtual/thermal/cooling_device0/cur_state file content says '0' and never changes.
/sys/devices/virtual/thermal/cooling_device0/type file contents says 'ath10k_thermal'

Thoughts?
