RSSI (<span><span>Received Signal Strength Indication) can be used, as the name suggests, to get an indication to what the signal strenght is. </span></span></p> <p><span><span>The RSSI is not the best option for accurate measurement of distance because physical obstacles, noice from other radio sources etc. will impact the RSSI.&nbsp;</span></span></p> <p><span><span>Q3: </span></span></p> <p><span><span>Not sure if I understand the question. But if you have server nodes with the health model publishing its status, you can have your client node subscribe to thos nodes. </span></span></p> <p><span><span>Br, <br />Joakim</span></span></p><div style="clear:both;"></div>
