I’ve had Vera Lite for just over 6 months now and I’ve been running scenes with schedule or triggering them by other devices. Now I have an idea for ventilation in our winter garden. It involves comparing indoor and outdoor temperatures and turning on ventilation (fan) in certain conditions. For example:
IF indoor < 25 C & outdoor < indoor = OFF
IF indoor < 25 C & outdoor > indoor = ON
This would allow warmer air to come inside the house. However as winter garden gets too hot at certain times there ought to be a tipping point in temperature (25 C).
IF indoor > 25 C & outdoor < indoor = ON
IF indoor > 25 C & outdoor > indoor = OFF
This would turn the ventilation on when air inside is too hot while outside it is fresher.
How would one go about doing this without really knowing lua and PLEG (which everyone is talking about)? Any help including linking me to apps or similar thread would be welcomed.
