Does the controller have battery backup? If not, what happens when it loses power?
ingme233 No, not even a button battery.
ingme233 Hi, which model are you referring to? ImoLaza mini and ImoLaza ET controller have no battery, while ImoLaza Ultra does. However, even with battery backup, it's not designed for running when there is a blackout, but for time calibration.
ingme233 What you're looking for are antiques, 90s products.
