I’m building a watering system for my grandparents garden. Hardware and software is set up and now I have to program the automation.
I’m thinking about 2 scenarios to control the watering system.
No. 1 : Hass.io server at my grandparents which is accesible from the internet. If I have to change something I have to log into their system. However, I would have to set up the system and buy a server (raspi or similar) which has to run all the time. Not my prefered solution.
No. 2: I can control the system remotely from my own Hass.io installation. Easiest way I can think of is to use an online mqtt server like hivemq. However, how can I control hivemq from my hass.io and still use my own mqtt server which controls my apartments devices? Any ideas? I would really prefer this solution.
