Hey I have some PIR’s linked up to MQTT through a Sonoff-Tasomota flashed bridge. Can anyone tell me what the data means? I understand the Data segment but what does the Low and High and Sync mean? I think the low and high has something to do with the sensitivity but i cant work out the scale

08:43:11 MQT: tele/sonoff_bridge1/RESULT = {"RfReceived":{"Sync":12210,"Low":410,"High":1170,"Data":"826C86","RfKey":"None"}}
08:43:19 MQT: tele/sonoff_bridge1/RESULT = {"RfReceived":{"Sync":12240,"Low":400,"High":1180,"Data":"826C86","RfKey":"None"}}
