Meaning/pronuncation of 祢 祢

Google says it means "you" and is pronounced "mí"

Wiktionary says it is "you" but only for deity and pronounced “nǐ”

My pinyin input method offers it for "mi" or "ni"

CEDICT makes it a "memorial tablet in a temple commemorating a deceased father"（or a surname) and pronounced "mǐ"

I'm guessing all three meanings are correct, but that would mean at least one of the pronunciations is wrong (since Google and Wiktionary give it the same meaning with different sounds).
新华字典 only gives mí, meaning the temple of one's deceased father, an ancient word.

Also in some Christian texts, 祢 is used as a variant of 你 to address the god, I'm not sure but I think it's because the character 祢 happens to be 神 and 你 combined. In this case, of course, it's pronounced same as 你.

Neither meaning is widely used today. In fact, the most possible place where you may still see this charactor is 祢衡, name of a Chinese historical figure.
