In my ignition module I was able to get basic reads and writes working by creating a TagProvider (with an empty Security context for testing). Based off the example in the [sdk docs](https://www.sdk-docs.inductiveautomation.com/docs/appendix/tag-examples/read-and-write-tags/) But then I saw that the github [sdk example](https://github.com/inductiveautomation/ignition-sdk-examples/blob/9ba2194dcd9d5f95f302e6c7abca4904d0f734d3/managed-tag-provider) is using a ManagedTagProvider instead. From @Kevin.Herron's reply on an [older post](https://forum.inductiveautomation.com/t/type-of-tagproviders-managed-or-standard-what-is-diffrences/65904) it seems ManagedTagProvider is the recommended way to do it? If I already have the basics working with TagProvider is it worth pivoting now? I don't want to run into issues down the line from doing something unsupported. There's an added caveat that the I'll need to be updating a dozen or so tags simultaneously, and the TagProvider supports that with `writeAsync`. ManagedTagProvider seems to only support a singular `updateValue` at a time. ---

You should not be using `.writeAsync` to deliver data to tags from **inside** your module. That method is for **users** of your data to write **into** your module. The ManagedTagProvider is structured to make it easy for module developers to provide the inside data supply. If you implement the `TagProvider` interface, you are entirely on your own. ---

I didn't have to implement the interface myself. From the GatewayTagManager I was able to `getTagProvider()` and use an existing implementation. ManagedTagProvider has `updateValues`, but I don't see a way to read tags into the module. Is there a different interface to use for that? ---

So... you didn't actually create a TagProvider then? You just got ahold of an existing one and used it to read or write to its tags. Which is fine, but it's not _creating_ a TagProvider. ---

Oh no, I didn't implement a new one. That was confusing wording on my part. I got an instance of (something that implements) TagProvider from the GatewayTagManager. From the GatewayHook's `setup` I took the GatewayContext and then called ` context.getTagManager().getTagProvider(TAG_PROVIDER);` It works for me now, but I don't want to leave landmines for myself to step on later by using an unsupported interface. ---

This is fine. Creating your own TagProvider (using ManagedTagProvider) is an entirely different thing that looks like it may irrelevant for you. ---

Got it. Thank you!
