PecanIoT Central Texas (verified owner) –
Even though these cost more, I like them better than the Dragino LDS02. They can handle faster door open-close cycles, their default update is quicker (yes I know about battery life) and the form factor works better and seems to fit better. Still – I made my own mounting brackets for these as I wanted something a little better and more flexible in the mounting location. for example – sometimes you have to make up a gap in the door – I have solved that. I use this sensor to monitor doors in AirBnB, cabins, and windows in my shop. My tech stack is DSL08 -> TTS on Linode -> Ubidots.
