Sorry about the lack of clarity: we’ve already started shipping OpenSprinkler v2.1 which has on-board per-channel TVS (transient voltage supressor) for protection against transient high voltages. So you do NOT need to purchase MOVs separately. All orders of OpenSprinkler 2.0 will receive version 2.1. I haven’t had time to change the webpage yet, which should be done within the next few days. Thanks.
