Decided to jump the badwagon and also increase my Homey’s range, as it was very bad in it’s original state. I have a very recently build house which apparently is isolated so well, that the z-wave signal wouldn’t even reach upstairs.
I followed above idea’s and the result is quite nice. I did damage the shell a bit when attempting to separate it, as it was glued pretty well and in the beginning almost impossible to get in between. But I just rotated that to the backside.
I haven’t fully closed her up yet, pending some last work on the inside and/or some last adjustments if results aren’t as expected., but boy she does look pretty now. Almost like a real magical creature…
The back antenna’s are the 2.4G ones for respectively WiFi/BT and Zigbee. The Z-wave antenna is actually inside the unicorn horn.
