Hi there.
I bough 10+ Shelly Dimmer 2s.
I have test setup in well ventilated room, ambient temp approx. 20C, using:
9 x Aurora Enlite 4W LED GU10 PAR16 Cool White Dimmable
2 x retractive (pulse) switches
240V supply with neutral connected.
Code
{"wifi_sta":{"connected":true,"ssid":"TitanNet_IoT","ip":"192.168.1.230","rssi":-60},"cloud":{"enabled":true,"connected":true},"mqtt":{"connected":false},"time":"13:19","unixtime":1626956389,"serial":1888,"has_update":false,"mac":"E8DB84D69C3D","cfg_changed_cnt":9,"actions_stats":{"skipped":0},"lights":[{"ison":false,"source":"http","has_timer":false,"timer_started":0,"timer_duration":0,"timer_remaining":0,"mode":"white","brightness":61}],"meters":[{"power":0.00,"overpower":0.00,"is_valid":true, "timestamp":1626959989,"counters":[0.000, 0.000, 0.000],"total":6473}],"inputs":[{"input":0,"event":"","event_cnt":59},{"input":0,"event":"","event_cnt":0}],"tmp":{"tC":48.77,"tF":119.78, "is_valid":true},"calibrated":true,"calib_progress":100,"calib_status":0,"calib_running":0,"wire_mode":1,"forced_neutral":false,"overtemperature":true,"loaderror":0,"overpower":false,"debug":0,"update":{"status":"idle","has_update":false,"new_version":"20210429-102101/v1.10.4-g3f94cd7","old_version":"20210429-102101/v1.10.4-g3f94cd7"},"ram_total":48200,"ram_free":35268,"fs_size":233681,"fs_free":119225,"ping_check":true,"uptime":66193}
Just after 25 minutes or so, it goes off - overtemperature (100C +).
At this point it's unusable, I can only imagine it heats up pretty quick inside the box or ceiling rose.
Is this bad design or firmware issues and has been sorted out?
