Looking for low voltage Alexa compatible iot module.

Hi, I'd like to convert an electronic cat toy to an iot device so that I can schedule some play times for when I'm at work. I want to just a module to contacts on the push button and splice onto the 3AA battery supply. The biggest issue that I've found is most of the modules require 5v or 12v. I'd rather not run a dc booster if I don't have to. Does anyone have a small module that runs from roughly 3.7v?

LoRa Help!

I'm trying to set up a LoRa network, I just got a PyGate, GPy, and LoPy. I'm have a hard time setting them up. I can't seem to find anything online about how to get them from the box to be set up. Is anyone able/ willing to call me? Or have any advice or ideas?

Cannot connect to Cumulocity via MQTT

Cannot connect to Cumulocity via MQTT

Hi everybody,

I have a question for those of you who used Cumulocity.

I'm just starting out with Cumulocity IoT using a trial account and this could be a simple beginner's misunderstanding but I can't seem to connect to my Cumulocity tenant using MQTTBox or python client. I have followed the tutorial but it just doesn't seem to work.

This is my domain name: env367812.eu-latest

I have followed a tutorial from this link: https://cumulocity.com/guides/device-sdk/mqtt-examples/#hello-mqtt) but when I enter my credentials it doesn't connect. I even tried the python examples and no luck there. The password is the one I used to login in to Cumulocity and the username is the email.

with eu-latest

without eu-latest

I tried two different links for connection, one without and one with eu-latest com since I didn't know whether to include it.
