I’ve just noticed that I’ve been getting blocks of missing data from one of my emonTx. Some may remember that I’ve got two - one in the house next to my emonBase and one some tens of metres away in the garage where my mains inlet is. It’s the remote one that is giving blocks of nulls, sometime for hours at a time.
The graph shows the radio signal strength from both emonTx. You may be able to see that prior to this month there have only been brief signal drop-outs, although there are three odd spike reductions in November (there are none prior). But since Dec 5 there are some noticeable gaps in the data.
My immediate thought is that the gaps are due to radio interference of some kind and the only thing I can think of are Xmas decorations, particularly outside Xmas lights. We have several neighbours who are quite keen on them!
Is there any way I can detect radio interference without special equipment? (What equipment would I need?) I’d like to get some confirmation before I go annoying neighbours with my concens.
Thanks for any help, Dave
