Found the following item on Lazada but am confused about so many types of power input/control. Will appreciate advice from an electrical expert as to which type of power input/control is suitable for the environment in Malaysia.<br /><br /><a href='https://www.lazada.com.my/products/rain-and-snow-sensor-heating-anti-freezing-jtion-waterproof-rs485-4-20ma-rain-and-snow-monitoring-automatic-weather-station-i3065053616-s15270694065.html?clickTrackInfo=undefined&search=1&spm=a2o4k.searchlist.list.i40.3d04628eqCwcbU' target='_blank'>https://www.lazada.com.my/products/rain-and....3d04628eqCwcbU</a><br /><br />I guessed the heating feature is for a snowing environment so not necessary to have it in Malaysia.<br />But very confused as to the type of power input/control - RS485; Relay; RS485+Relay; 0-2V; 4-20mA.<br /><br />Thanks in advance for any advise. nikobellic Serious Kopitiam Wed, 28 Sep 2022 11:48:15 +0800
