The D-024 remote has been developed to take over from the D-022. It uses LoRa modulation, which accounts for the long range and stable connection: in an average city the remote will be able to receive and trasmit signals at a distance up to 1,5-2 km (1-1,2 miles).
The remote has a built-in accumulator and it can go without charging 20% longer than the D-022.
