Lightning node red

Laci All Messages By This Member #14360 Hi guys , can the Lightning node red application control a switch ? If I am not near a computer and lightning activity is closer than for example. 5km then turn off the radio and the amplifier. 73 DE Laci HA8RD

Puneit Singh Member Profile All Messages By This Member #14362 Hello Laci AMS AS3935 Franklin Lightning Sensor can detect lightning near your QTH. Once detected, nodered can be used to control a coaxial relay or if using a mechanical relay, a servo can be used to control that. You can use ESP32. If you are using HomeAssistant, then setting up sensor is quite easy via Esphome. 73 Puneit / VU2TUM
Marty Boroff All Messages By This Member #14363 There is a node-red flow that polls the litigators site and tell you how far away a lightning strike is detected. There are a couple of different flows in the file section. No need for any sensor hardware.

Laci All Messages By This Member #14364 I am using the W8BE node red lightning flow , which I would like to use to switch a relay that disconnects the amplifier.
Marty Boroff All Messages By This Member #14365 Laci Ok. Sao what is the issue. you need to connect some relay board to your node-red server. Enter you longitude and latitude in the function and if the result of the caclulation is less than some number send a message [payload to the relay to turn off the amp. later turn it back on.
