Finding Code for built in drivers

🧰 Built-In Apps and Drivers
1

I use several IP-driven switches with a community HTTP driver which works fine.

However many of the devices need a "button or momentary on action" in the same way as the built-in virtual switch driver.

By way of a learning exercise, I want to try and modify the driver myself.

Question: where can I find the code for the built-in virtual switch driver so I can learn what I need to alter in my HTTP driver!

Thanks

Unfortunately the code for the built-in drivers are not made available. But if you need assistance with developing / enhancing a driver there are plenty of developers on this forum than can help with any questions you may have. If you want to ask a question though, perhaps post under another thread with a title relating to your question.

EDIT: By way of an answer I suggested you post in a different thread :slight_smile: ... Scheduling options may be something that you need to look at. I may be able to assist by documenting some of the approaches I have taken in my drivers, but there are also notes on other threads.

Hubitat does publish a few sample drivers. HubitatPublic/examples/drivers at master · hubitat/HubitatPublic · GitHub

I am not a coder of any type, so I am not sure if these will be helpful or not.

I just threw this together quick (including some copy/paste from another driver I had already written :slight_smile: ), and it is likely more or less how Hubitat's internal virtual switch driver was written if you do still want to use that as a starting point. To be clear, this is a "reverse engineered" community driver that is similar (identical?) in functionality; as mentioned above, the built-in drivers are (mostly) all closed-source:

Thank you very much. This is exactly the functionality I am looking for. I think I can now integrate this into the HTTP switch driver.

Again, Much appreciated.

There are a ton of community drivers and most are posted publicly. So you can always base a driver off what someone has written before and most developers are totally happy as long as you give them credit.

For example, I usually have a Thanks section at the end of my opening comments just before the actual code starts.

With the help I got from Robert Morris I was able to make the changes I wanted to the HTTP Driver I currently use. It's now tested and working just fine.

I am just posting it here in case anyone else finds it useful.
