Is there a way to lock the switch to ON so that my P110 can be used as a power monitor without the possibility of accidentally turning it off? 

e.g. My P110 is monitoring the energy usage of a PC. In the phone app it sits right next to a camera used as a baby monitor. So I've shared the app with other family members. It just looks far too easy for them (or me) to accidentally turn off power to the PC when looking at other things in the app.
