sms-forward-bot

Forwards all SMS received on Netgear LB1110 to a telegram group.

Practical uses:

• "Redirect" two factor authentication messages to telegram

Important notes:

• Due to limitations in LB1110's software, every forwarded SMS gets deleted on the modem.
• Due to limitations in LB1110's software, sms with multiple newlines may appear as multiple messages.
• Modem password and sms are transmitted over http (not encrypted). Don't connect the modem to your network, hook it directly into your machine.
