so my idea is to increase the scope of the network and be able to also measure the Wall Plug module Fibaro
razberry range problems
How to do it?
Dear PoltoS,
I would like to try it on my own risk.
I just learned that one uses a small UFL connector and then plug a pigtail will the real SMA onto it. The SMA will then get screwed to the case.
There is a little resistor right before the long line of pcb copper. I assume this is one of the poles of the antenna. Since your suggested model is a dipole antenna, where would the second pole go (or come from)?
And which of these is the inner and outer pole of an UFL/SMA or reverse pole (RP)-SMA? I suppose it matters which is which
Once I know where to solder it I would procure an SMA.
The thing is, I could really need some range extension.
Today I tried to install Fibaro window reed sensors and the connection won't make it to another floor. I already knew it and tried to optimize it but didn't succeed too much.
I will also install a few mains powered devices (in contrast to battery powered devices) that can act as a router but for the reed sensor with the longest distance to the Razberry there is no possibility to bridge the gap at an optimal place.
So a photo or a sketch with two marks where to solder the SMA plug including polarity would be really beneficial.
I really like your product, especially the Javascript software. I already use hooks so my own functions will run if events are triggered...
... this is really nice, especially for the price and the RPi as a device to learn all sorts of things, e.g. z-wave.
edit:
After a little research I think the two poles are already there.
Are they the two little solder spots on the opposite of the resistor connecting the pcb antenna?
Looking on the Razberry as pictured on your website: The upper one would be ground, the lower one right next to the resistor leading to the antenna would be signal?
Well anyways, any information would be really appreciated.
Kind regards,
peter

Aeotec - Rage Extender Z-wave
Hello,
apparently Aeotec announces Z-Wave repeater to extend the network "Rage Extender Z-wave "

New Antenna
I just want to let you all know, that I successfully added a new antenna to the razberry. I bought a 868 MHz antenna and added it without an additional capacitor to the two soldering spots next to the build in antenna.
It works like a charme. The range roughly doubled.
Once I wrote a blog entry on my website I will come back and leave a link. There will be additional information how to do it and also some pictures.
Kind regards,
Peter

Looking forward to that!

The device from Aeotec is
The device from Aeotec is pretty useless, since almost all Z-Wave mains powered devices are repeaters

Additional Antenna Added
Hi Guys,
Although this is quite old now, I just couldn't get my Razberry working past a few metres. All is now solved, complete with a blog write-up.

Interesting, just one
Interesting, just one additional question:
- Shouldn't the wire antenna actually be soldered on the other side of the cap and that side of the cap disconnected from the pcb board antenna? Otherwise it looks to me as if you add an additional antenna in parallel to the existing one. How is this going to impact the total impedance, is this optimum?
Best regards, Walter
