Hi Hilary, all good am still in china snd heading back tomrrow to uk.
China was on national holidays from 30 April to today May 5.
Now working on it.
I have discussed with the team - Due to small number of meters for the system, we suggest a cloud version so you don’t have to invest in hardware. Many endusers are doing this.
Meters we can handle but MOQ is around 2000 metres.
Or we can manufacture them to very with other orders. So you don’t have to worry about MOQ.
