Wi-Fi or your smart device's own Internet. If you live permanently in a place where a smart home system works, the first option is more cost-effective: you don't have to pay for additional Internet. However, in this case, you are completely dependent on it, and this is not always convenient, as the Internet via Wi-Fi may turn off at the very moment when you are not at home.
For a country house, where you don't visit very often, only independent viber database Internet via a SIM card is suitable. There is no point in paying for Wi-Fi there all the time, but smart sockets, gas sensors, pipe pressure, smoke and leaks are necessary there.
Tariff selection
A smart home requires a separate SIM card with a tariff focused on the Internet and low traffic costs. At the same time, it should not have any additional services or options.
MCN Telecom has a special IoT tariff for this. It includes 100 MB and 100 SMS per month for 49 rubles per month. In most cases, this is more than enough for a smart home system. However, if the Internet package is exhausted, you can buy additional traffic and SMS - 0.06 rubles / MB and 1.20 rubles / SMS.
