SignalR

Can we use asp.net SignalR for controlling remote connected devices (not a computer or mobile just an electronic device having its uniuque mac address) from control server? Server will decide when an alarm is supposed to ring from the device and if user not responded to the alarm then the device should send back some kind of signal or message to central server that alarm was not responded.

Devices are always going to be connected i.e. online. There is going to be to and fro commands/message/request-response between central server and remotely connected devices. If you have solution other than signalR, please, suggest me.

Thanks in advance.
