Hi JScott
I look after 15,000 devices in over 100 schools with Senso. Everything you mention is possible in Senso, plus more, and with the impending update about to drop, scheduling shutdowns and WOL will be a dream.
The response from schools to Senso has been nothing but positive. In comparison, our previous software, schools weren't interested, and it eventually never got used by teachers.
Safe guarding element is amazing for us. We have over 3000 violations today. Having the ability to spot trends really helps us support our schools. If you want to speak to me more about our setup, I'm sure the guys at Senso will put you in contact with me.
