2/18: Critically Low Battery
-
2 days prior I had just replaced batteries on another sensor that also had Critically Low Battery. Those batteries were replaced even though they tested 100%. That one with new batteries installed supposedly reads at 40%. I replaced this sensor’s critically low battery (also tested 100%) with brand new Energizer Ultimate Lithium batteries and now won’t turn back on. All 4 sensors have the same type of batteries. 2 in the backyard still read 100%. 2 in the front yard both having issues. Backyard sensors are 115ft and 75ft from WiFi router. Front sensors are 85 and 88ft from the router.
-
front sensor (337HRX) is on but not working correctly. Detects watering (rain gauge reads 1inch) but Soil Moisture % stays level.
-
Front right sensor (3359YF) hasn’t turned back on since replacing batteries. But then again it died with 100% batteries before replacing.
