My phone just lighted up. POWERMASTER 10 told me something. It said “POWERMASTR 10: KOM OK”.<\/strong><\/p>\n\n\n\n

Over the last few months, I’ve received almost 30 weird text messages from a “POWERMASTER 10”, originating from a Swedish phone number in a number range reserved for “devices”. Yeps, I’m showing the actual number below in the screenshot because I think it doesn’t matter and if for the unlikely event that the owner of +467190005601245 would see this, he\/she might want to change his\/her alarm config.<\/p>\n\n\n\n

Powermaster 10<\/a> is probably a house alarm control panel made by Visonic. It is also clearly localized and sends messages in Swedish.<\/p>\n\n\n\n

As this habit has been going on for months already, one can only suspect that the user hasn’t really found the SMS feedback to be a really valuable feature. It also makes me wonder what the feedback it sends really means.<\/p>\n\n\n\n

The upside of this story is that you seem to be a very happy person when you have one of these control panels, as this picture from their booklet shows. Alarm systems, control panels, text messages. Why wouldn’t you laugh?!<\/p>\n\n\n\n

Edit:<\/strong> I contacted Telenor about this after my initial blog post but they simply refused to do anything since I’m not the customer and they just didn’t want to understand that I only wanted them to tell their customer that they’re doing something wrong. These messages kept on coming to me with irregular intervals until July 2018.<\/p>\n\n\n\n

Update, September 8, 2020: I got another text today (it’s been silent since September 26, 2019). The Swedish text in this message translates to “battery error”.<\/p>\n\n\n\n
