      Lightning detector

      I bought this to expand my system. It was easy to install, and it set up straight away on my consol. It is hard to find a PWS with this feature in the UK. Most lightning equipted PWS come from the US which can not be intergrated into an 868mhz system.

      I had to set it to minimum sensitivity as it was picking up our boiler ignighting. I have placed this outdoors and was eagerly awaiting a storm. Sure enough a few days later we had one and the results were incredible. If tracking lightning is your thing I would highly recomend this add on sensor.

      All set up

      Well what can I say?
      Am just waiting for lightning to be honest so as soon as we get some I will update this message. :-)
      It was so easy to set up just pop the batteries in check the switches on the back and put together the shield which is just 1 screw to hold it in place and then bolt to to the post hey presto done in about 10 minutes if that :-)
      It goes well with my wittboy :-}

      Confusing DIP switch documentation

      I've had this unit for several months, and in all that time it had detected nothing, so, after the big thunderstorm a few nights back during which it detected absolutely nothing despite the lightning being directly overhead, I finally went asking questions.

      I learned that the unit had arrived with the DIP switches in a non-working position. The documentation is very unclear, but it turns out that the correct default setting is with all the DIP switches pushed down towards the battery compartment. Mine had arrived with them all pushed up away from the battery compartment, That looks reasonable when compared with the documentation (and the details on the back of the unit), but, unfortunately, it means that the antenna is disconnected.

      I have now changed the setting to the correct default (with all the DIP switches pushed down towards the batteries) and my unit detected its first ever strike last night.

      We have not clarified the products switch settings with additional images on the product description. I am sorry to hear that this was received incorrectly set fro the factory.

      Easy to setup and use

      Thanks Weather Spares for the quick shipment and no fees. Easy to setup and detected its first strikes a few days ago.
