The plot thickens... after getting everything re-associated, it has failed AGAIN. I am able to set and unset the alarm using keyfobs, but the online portal doesn't work- there's no connection to the gprs unit. Strange though as the gprs unit now has a solid green light and honeywell technical support are telling me they can see it communicating with their systems. Because I cannot use the portal I have been unable to pair my external siren, which means that although it's fitted to the building, I've had to remove the batteries as it kept beeping, keeping us awake.
As it stands I'm days away from ripping the whole thing out and returning it to securitywarehouse. What a heap of junk. I should have bought a supposed less-secure system from Yale or First Response. At least it would have worked reliably and cost half as much.
Admin, I think so too. If I don't get anywhere today speaking with Honeywell, I'll return it to you for a refund/replacement. Feel free to contact me.
