So far keeping Deity in your separate house, I think there is no need for this. Because if you keep Him there, you have to take proper care, with aratis and attention, and thus divert attention from the Deity in the temple, and from chanting and so many other forms of service, like your writing and sewing, etc. So I think it best if everyone centers his attention on the Deity in the temple, and in that way the temple worship will pull on nicely. Of course, if the temple is unapproachable, or too far, or something like that, that is different thing, but if the temple is easily accessible then this is the best program - for all to go there and attend arati and kirtana etc.
