Added Security Feature 

The customised version of Tasmota installed by UBWH has an added security 
feature. If the 

Permitted WAN IP4 Address

 is NOT 0.0.0.0, then http 

commands coming from outside the local network (LAN) will be rejected 
unless the source address is as specified. 

 

  

 

A command request looks like: 

http://<device.ip.address>/cm?cmnd=xxxxx
