-You can also subscribe to hmslasermonitor on [[https://​telegram.org/​|Telegram]] to receive notifications on the state of the cutter. If the temperature becomes suspiciously low or high, a Telegram message is sent to subscribers.

Or it's on fire.+You can also subscribe to hmslasermonitor on [[https://​telegram.org/​|Telegram]] to receive notifications on the state of the cutter.
