P2P with LT relay and LSN-50 v2.2?

[Robotic Grow]

Hi,  I was wondering if it is possible to set the LT-22222 relay to turn on at 75°F and off at 68°F using the LSN-50 v2.2 Temp Sensor. I have accessed the serial monitor using a USB to UART adapter and need guidance on the AT commands required to accomplish this. I need to know which modes to set for the devices and if the frequency matters for peer-to-peer communication to avoid using a gateway. Can I set the two devices at 920 MHz? Any suggestions or the necessary AT commands would be greatly appreciated.

Hi, Grow, 

To acheive your goal. you need to have two features:

1) Point to Point Communication. LT-22222-L support this feature , but LSN50v2 doesn't support this yet. You can consider to use 2 x LT-22222-L. Reference: http://wiki.dragino.com/xwiki/bin/view/Main/%20Point%20to%20Point%20Communication%20of%20LT-22222-L/ 

2) Temperature Trigger. Only LT-22222-L can't provide the temperature Alarm Feature, Maybe you can consider adding such sensor together. https://www.aliexpress.us/item/3256806177846247.html?spm=a2g0o.productlist.main.67.61a4mVdlmVdliD&algo_pvid=9cd22fcf-3421-46e2-bdb3-1bbff8f15ef5&algo_exp_id=9cd22fcf-3421-46e2-bdb3-1bbff8f15ef5-33&pdp_npi=4%40dis%21USD%2113.93%2111.14%21%21%2113.93%2111.14%21%402101ef7017197587938095264e7f57%2112000036905232856%21sea%21US%210%21AB&curPageLogUid=LLXkO51CRZ39&utparam-url=scene%3Asearch%7Cquery_from%3A
