It depends whether you have a smartthings/Aeotec hub or not. If you do, then there is a community-created edge Driver for virtual devices which has a lot of options, including momentary. Please ask any further questions about that in the author thread:
[ST Edge] vEdge Creator: a virtual device generator for end users
If you don’t, there are still some options, which are in the FAQ which I gave you earlier today in one of your other threads, so you may not have seen it yet. So here it is again:
FAQ: Creating Virtual Devices with the new architecture (Without the IDE) (2023)
If there is not an actual momentary option, you may have to use a routine to turn the virtual device off again after it has been turned on each time. That works, but the minimum time will range from a few seconds to a minute, so a little slower than an actual momentary device. But still workable for many use cases.
If you want to discuss these options further, please start your own discussion thread so we can go into the details of your specific use cases. The general list of resources for anyone interested in virtual devices without the IDE is already available in the FAQ above, so that covers it as far as this thread is concerned.
