Help Getting Into Smart Home / Home Automation

Accidentally came across this just now detailing how to link multiple temp sensors onto a pi. I would assume it works the same way with the wemos.

Electrically, you can definitely do it.
I'm just not sure about the ESP Easy software. But the software does read the b20's address, and you have to select it when you setup the device, so the software may support it also.
Try it and let me know what happens ;)

I setup another b20 the other day, didn't work at first because I forgot the resistor :banghead:.
Once I added the resistor, worked fine. You just have to wait a minute or two for the temperature to show up.
 
Finally got this all installed in its permanent location. It could use some cleanup but I've still got an automatic door opener project to finish as well (not using home automation... Don't want to rely on a network connection to open/close the coop door). I'll be using a linear actuator to open/close the pop door at sunrise/sunset and a photo sensor. Hoping to add a few magnetic switches to the door to text me when it's open/closed as well.

Also, 1) thanks again for all you're help and 2) I did wire two sensors together using the same gpio pin on the board and one resistor and it's working just fine. Like you said, they have separate hard coded serial numbers that allow this. Easy to figure out which one is which just by grabbing one and waiting for the temperature to start rising.
 
Glad you were able to get everything working :)
i'm still amazed how cheap and powerful these little esp boards are, and when mated with espeasy makes it really easy to implement.
