Deliver very quickly, thank you

Everything is super, in addition, I can’t keep it up to ESP32 through RS485 (do not get it right and everything), such a nuance-The Annex address (for RS485) cannot be properly adjusted. I’ll get it into the shield-I’ll get it.
Such as having connected to home assistant through the tegratsia Tuya local (though with a dance with a tambourine).

Software errors present in the product. Most importantly, when electricity goes and goes, it gives electricity instantly without delay. The setting menu comes out on the screen every time the electricity goes and goes. Time to turn it on again when it goes to protection Min 1 minute. You can’t bring it down any further. The forward charging setting is made on the device.

The object only detects the smoke and not the gas as in the description photos

I can’t say a bad word about it. I’ve installed, download app and it working great! Then in app came a update and since that moment my frequency is 0.00 and power factor -9.99. I wonder whose to blame because Tuya says it’s not our fault.
