hello all
new to the forum
here's my first question i have a wh1081 and wondering if the st1 solar transmitter which is supplied with the 8681 would work with my wh1081 receiver.
thanks in advance
Gordon

Re: wh1081 solar power
Hi Gordon,
Well it definitely won't give any Solar readings and I'm virtually certain that it won't even charge the battery. The Solar cable has 6 contacts (RJ12, 6p6c) with I believe the charging voltage on one of the end pins, whereas the 1081 only has the four middle contacts fitted (RJ11, 4p4c). Also, I believe the voltage regulator may be in the transmitter module not the Solar Pod.
My advice is just to fit a pair of non-rechargeable AA Lithium cells to the 1081, which will probably last at least until some other part of the sensor system needs repair or maintenance.
If you really want to use solar power, then use ONE AA Lithium Phosphate (LiFePO4) 3.2 volt cell of reasonable capacity (>600mAhr) with a dummy (short-circuit) cell in the second bay and modify a "Solar Garden Light" from a Pound shop (not quite a trivial mod, details on request).
Cheers, Alan.
