Hi I have been using the code mk3 with artnet for some time. Now I have a need to control dmx from a browser, and unfortunately browsers cannot send udp data, so I can't use artnet. Is there any way to post dmx data to the ode devices? (Or any other device that can do that)? Thank you

Hello,

Within the ENTTEC range the closest thing to being able to do that would be the S-play where you could send the desired values over HTTP to create/edit a Cue and then Tell it to play the cue.
However some logic with the S-play like that it stops all cues when the cue editor opens could make this channelnging. If you knew what scenes you wanted before hand however you can create then all and then just call for them to play and stop as desired?
S-Play Lite:

S-Play API:

Are you able to provide some more insight into your usecase?

Hi Thank you for the information, I'll definitely take a look at the s play. Our use case involves a system which among other functions involves colored status indicators. Each installation could have 20 or more colored (RGB) indicators and we need to change the color of each light as the status of a particular unit changes. We have the system installed on site at several customers using a .net program and artnet with the ode mk3 and it works great. We are now exploring offering a cloud based version of our system and we would need to be able to control the lights with our software running completely in a browser. So we are exploring what options 3 have for control from a browser.

I checked the s play api quickly and it seems geared to running pre-recorded commands which wouldn't work for us, there are no 'scenes' in our system, each light operates completely independently of any lights, I would need the ability to control specific addresses. I see one of the commands is UDP_MESSAGE, but that I'm not clear at all if that is what I'm looking for and if that would allow me to send udp data (as in somehow sending 512 numbers to control the dmx output directly)

So I'm thinking perhaps I can setup the device to play a single cue and I can use save_cue to change the dmx values for that cue? would that work?

If I understand correctly according to this page: https://www.enttec.com/light-show-control/#comparison, the http api is only available on the s-play sp-1 or the s-play lite, but not for the s-play mini or s-play nano, is that correct? (the sp-1 and lite are far more expensive)
