Buy a mobile phone jammer - mobile phone jammer china
That’s quite a plan, you’ve got there! First of all we should tell that we at jammer-store.com have lots of devices, suitable for the task you have described. I suppose that it will be better to have a small and portable device, that will be able to block that smart thermostat form 10-15 meters (30-50 feet) distance. That device will block all the Wi-Fi signals in the area, so your neighbor won’t be able to control the thermostat over Wi-Fi.
Wi-Fi uses a 2,4 GHz frequency to transmit data and our Wi-Fi jamming devices are emitting signals on the same frequency, so it is overwhelmed with white noise. The whole process is really simple and you will have just to push the button and the device will start working, then push the same button again and it will stop.
You will also have the chance to protect your and probably hers wireless network from all the Wi-Fi vulnerabilities. So, when you turn the device on – her thermostat will stop working and when you will come to repair it, simply turn that portable Wi-Fi signal jammer off and everything will be fine. Her device will be operational and you’ll look like a good guy with excellent technical skills. Good luck!
Thanks for your question, I hope, I’ve managed to help!
