I don't think this portion of the topic has been discussed: temperature monitoring. Our GH is ~2800 square feet, double poly tunnel style. We're in Zone 5, and winter heat minimum is set to 62F as a low for tropical plants. We use geothermal heaters. A geothermal heat pump exchanges heat between the ground or water source and the air to heat. We are using the pond for the geothermal loop. The heaters use electricity, and also have the capability to use propane. One of the temp monitoring systems we use is a T&D WIFI Temp Logger. It can send emails or an audible alert. I've included a screen shot of some random data. It's been extremely useful when trying to determine a problem. Because our internet is sometimes sketchy, we also have a secondary alarm system. I have 2 sensors on the GH, one at the back end (120' away from the house) and one in the front. The main station is upstairs in the house where the system has line of sight to the 2 sensors. It will beep if the temperature gets too low. I would also like to figure out some smart device to connect to my Amazon Echo device, so I can ask Alexa to verify the temperature. I haven't figured out how to accomplish yet. Something like in the movie 2001: A Space Odyssey. "Dave, we have a problem....". I would be interested to hear what others are using.
