Just another update, noticed Lock was struggling a little last night to actuate the lock. Looked at battery % in ST and it said 97%. I replaced this morning with new Lithium batteries. They lasted just over 1 year. Since the battery reporting doesn’t work with these the audible difference is needed. @RBoy is there a way to update the battery algorithm in the DH for Lithium? I realize the window is much shorter but there is a drop in %.
