Smart devices

Hi just a question, I have been offered by Rogers a cheaper plan (WI-FI & tv) but I have security camera, thermostat and garage door phone access. We are on the trial period of Rogers right now and I saw that the camera and garage door does not work anymore since it is connected to TELUS Wi-Fi but the thermostat still works. My question is would the thermostat and the controls on the app still work even if I'm not with TELUS anymore or do I have to change my thermostat as well? Thanks
