Comwifi is not reliable enough to have it monitored for drop outs.
Go monitor hardware and turn off ATS faults.
Or like above, turn off notifications, get a gsm com on com port 2 with virgin sim unlimited texts £5 a month. You'll still get a notification if power goes out/your router drops out.
You'll probably find Sms commands to be enough for your remote control needs too. Just a suggestion )
