[ZIGBEE] 20A Zigbee socket with energy metering (Tuya TS011F_plug_3)
Welcome,
I bought my first Zigbee socket, taking advantage of the fact that there were promotions on Ali, it came out to about 10,50zł.
Exactly at this seller: https://pl.aliexpress.com/item/1005007256414108.html
Today it came to me with the rest of the shpeju and I would not be myself if I did not start by taking it apart and see what is inside. And it is well... judge for yourself:
- a protective cable from the "pin":
.
- capacitor(s) on the low voltage side 470uF/10V:
.
- where is the stabiliser from 5V to 3.3V?
.
And it doesn't. It is likely that the BP2525 inverter chip is set to 3.3V mode. And the relay itself is on 3V instead of 5V.
- The Zigbee module itself is also quite mysterious:
.
- Only the BL0937 chip from energy measurement standard:
.
When I saw this my first thought was, this cannot work well and.... I was right. After adding it to Zigbee2Mqtt and displaying the model description, it turned out:
- a lot of people report that the socket automatically shuts down
- the socket doesn't automatically report indications of voltage, current, that's why they did a polling every 60s (default, you can change this time or turn it off completely)

I took a quick measurement with a wattmeter, the switched off socket draws about 0.1W, while the switched on one draws 0.7W. Something a lot this 3V relay draws.
I'll now leave the socket on for a couple of days and see if it switches itself off. I think these switch-off problems, if they occur, are from an unstable power supply.
EDIT:
I'm also throwing in a photo of the thermal imaging about 40min after switching it on. There is no tragedy.

Add a commentAll powered from 3.3V? I don't think I've seen that before. I wonder how much they saved by removing those LDOs. And the power_outage_memory option works? Supposedly it should remember its last state... [Read more]
I haven't checked the power_outage_memory yet, I'll check. For now, the plug has been with the relay on since yesterday and so far it hasn't switched off by itself. I also found a review of this model... [Read more]

Well, for the thickness of the PE wire, this deserves a denunciation to the OCC because this wire will not carry 16 A long term, which is what it is obliged to do. That is to say, dangerous electrical... [Read more]
