We bought 5 dimmer caseta + pico we installed and was working fine until 3 days ago, all green lights turned off and dimmer stopped working, it happened at night but in the morning worked all good, then at night was working fine and we turned off before going to bed and happened again dimmer stopped working. I have checked the load is working fine I connected directly to energy and worked fine, also I checked connections and no sign of short circuit or temperature damage.
