Problem with mcModule case working with magnets
« on: May 03, 2017, 01:11:11 am »
Hi,

I just received the mcModule cases which are great and they came with little magnets for the reed switches which I though was awesome. unfortunately it seems that the way the agents have been placed inside the little piece of plastic means that it will never tricker the reed switch if they are aligned.. It only triggers if you misalign them which is unfortunate.

Has anyone else come across this?

Regards,
Michal

Hello.
Yes, I have the exact same problem.

But when I installed them on my doors then I installed a magnet (one of the two from the case) inside the wooden frame instead and that turned out nice.

If only they had offset the magnets inside the bit if plastic.

I don't think the solution you have employed would work for me as the magnet would be too far from the sensor.

It does. make me wonder about the possibility of sticking a magnet in the top of the door and having a tiny reed switch drilled into the doorframe and connected to an MCU up inside the ceiling. Could work for upstairs where I have ceiling access.

I use a small separate magnet, intended for magnetic door sensors. It's the same size as the one that comes with the case, and is a small, white pill shaped, self adhesive item. About $3 each.  See here https://www.aartech.ca/vip120-2c/flair-pill-style-surface-mount-door-window-magnet-only.html

This is what it looks like https://www.aartech.ca/vip120-2-flair-pill-style-magnetic-contact.html

Works great, gap can be 15mm and it still works. I have photos in my post on this forum about my door sensor (see here http://mcthings.createaforum.com/mc-innovations/front-door-sensor-via-mqtt/. I now have my door sensor in an MC case, but use the same magnet.
