FIX for broken B&Q/"Airforce" PM30 Electricity Tracker
by Matt at 2010-12-10 09:42:57 (Blog::Simon)
For all of you who have an out of guarantee, broken energy meter (probably everyone by now) then there is a fix, if you are good with a soldering iron.

The device uses a capacitive dropping transformerless powersupply to power the electronics which measure the power being used. You can read up more about at http://ww1.microchip.com/downloads/en/AppNotes/00954A.pdf.

What happens is the capacitor degrades with time due to all the spikes in the mains electricity for which there is not a decent filter to protect it from. This then means that the circuit inside does not get enough current to operate from, and it will continually read 0.00. If you replace the large (mine was yellow) capacitor with an N69CN from Maplins it should work again. I had to do the two button reset mentioned elsewhere to get it all to work again. I will try and get a full tutorial on http://www.diyelectronics.co.uk if I find the time.

Hope that helps someone.
