Pictures to follow but I got the WH32EP installed, probe clamped in place by a modified M25 gland, had to increase the internal opening 1-2mm, allowed the probe to pass through without disconnecting any wires. The WH32EP transmitter unit was installed in a Wiska 1010 IP67 housing, this was fitted with a M32 gland, again, allowing probe pass through. I have then added an extra soft rubber grommet, to seal the oversize M32 gland around the cable. Pretty painless once I figured the plan, it was dark when I finished so will partially disassemble for some images in due course. Big fan of the Wiska housings, unique design which isolates internal space from the wall fixings.
