fields. However, if there is still no acknowledgement after the second attempt, it will not retry a
third time, because the 3

phone number field is empty.
Auto acknowledge time on the local hydroSpider2 alarm is set to 60 minutes. Hence, 60 minutes
after the alarm trigger, the alarm will be auto acknowledged. This will allow the alarm to send a new
series of SMS commands if the water level goes inactive (above 1m) and then again goes active
(below 1m).
The Auto Acknowledge Time of 60 minutes ensures that remote SMS commands are not sent more
often than every 60 minutes, which could happen with water levels that change quickly.
Using the same logic, another alarm could be setup on the local hydroSpider2 to turn the pump off.
Its trigger would be Water Level Above (for example) 2m and the Message should be ‘OFF REM1’,
with all other settings identical to the alarm described previously.
