Hi Howard,
I’m building an Allsky just next to OCS, from time to time the camera under the dome will need some heating when humidity and temperature reach a certain level. An idea has crossed my mind that would be the possibility with OCS to give the sensor values to avoid installing new sensors. As OCS is a webserver i thought it would be possible to generate an xml output when a request is sent from a client. I really don’t know the effort  that would be necessary to make this but the idea seems interesting to me. I know how to program a small board (nano, micro) with a simple web client page, collect parameters from a webserver with actions to launch.
It is not a demand but a question as I know you are very busy with Onstep environment we are all enjoying.

Thanks in advance for your answer
