Temperature Sensor in Mineral Oil

[Ranchitat]

I have another SNZB-02 in between the HE and pool sensor, so I assume that the real distance will be about 15' repeated.

Battery operated ZigBee devices don't repeat. You'll need some sort of line powered device.
Or something like this: @rocketwiz made an Ikea USB repeater into a battery powered device.

Ok here is my redesigned battery backed tradfri repeater. On a 2000mAh battery power outages killing your mesh will hopefully be a thing of the past!

Please excuse the messy hot glue wire strain relief mechanism.
