I have a new v3.3 with the hardware ethernet module running the latest version of firmware 2.2.1. This is to replace an older v1 with 2.1.9. I poll the opensprinkler every 10 seconds, and the old one worked like a champ since 2017. No network issues, very reliable.
After about 2 weeks, I found the v3.3 dropped off the network. It could still be controlled with the local buttons, but didn’t respond to any network requests. A power cycle and the device is back. Has anyone else seen this with the latest hardware and software, or have any suggestions or advice? There was one comment about network switches. I plug the OSP into a managed TP link switch: SG3428X. Don’t know if that is an issue or not, it wasn’t for the older device.
