Thanks Howard for your efforts: I downloaded the latest OCS version 2.33, and set it up for my observatory
You are right for the relays. I returned to HIGH in lines 110 to 124 of OCS.ino so that it defaults normally closed when no control from the OCS is present, so it effectively reboots without troubles. However it reboots, quite randomly.
7. as 6. plus Weather charts ON : No change in the unsatbility status and charts are all empty. I will try to reload the Chart.js file but I am pretty sure i had the correct one in the SD card root directory. It does not need to be executed or run ? Just put in the SD card and that's all ?
8. As 6. plus sky IR temperature : still random reboots (perhaps a bit more frequent - my feeling) but all sensors that are physically connected to OCS are displayed correctly :
Are there any debugging codes that could be useful for me to improve my investigation ?
That's all for now.
