Reliable greenhouse Temperature Alarm
Built my greenhouse in 2012. at that time I got a LaCross Technologies wireless alarm that is supposed to send a text and email when the temperature fluctuates beyond levels that can be set.
The first year it worked quite well, after the initial subscription ran out I renewed the subscription and have had nothing but trouble. the tech support is lousy and the device is no longer very reliable.
Does anyone have another option? I do not want to spend $1000 nor do I want to have to run a phone line to the greenhouse. What are you using to monitor the temperature on cold nights?
