No progress this weekend but I've got my NODIZ on order.
It seems to be a step up from megajolt as it has bluetooth for mapping and a funky android app, think there may be some data logging add on functionality coming to.
If you take out the cost of a EDIS 4 module it only a bit more pricey than a megajolt.
Next step sorting out some of the wiring and running her up with the NODIZ
