EL450HA: Connection to device succeeded but no datapoint returned #1750

Open ronsnyder opened 4 months ago

ronsnyder commented 4 months ago

I have a Arlec LED batten Product Codes are ... "category": "dj", "product_name": "EL450HA", "product_id": "v00jsoknheiucj3u", "biz_type": 18, "model": "EL450HA JLD-2", It works well from the Smartlife app.

The interesting issue is the Tuya Protocol is 3.5 TinyTuya scan provides : Unknown v3.5 Device

I can control the device in TinyTuya if I set d.set_version(3.5) otherwise the device is not controllable from HA (can't set the protocol) or TinyTuya without using the 3.5 protocol.

same issue here. Cannot configure newly acquired Tuya bulbs with local Tuya. Tiny Tuya does not work with new bulbs unless using protocol 3.5

new bulb using firmware 2.9.15 old bulbs using firmware 2.9.6
