I’m using these zigbee outlets to monitor my server and they have been rock solid so far.
PROS
- Cheap at around £10 each.
- 16A relay, which gives it enough overhead for most devices with a 13A fuse.
- Small form factor allows you to place 2 side by side in a double socket & doesn’t obstruct the switch.
- Reliable (but see the cons list).
- Child lock switch which disables turning off the plug when pressing the onboard button.
- Power outage memory setting to dictate whether to turn back on/off after a power outage, or whether to default to the last known state.
- Fully supported in Z2MQTT.
- EDIT: They act as zigbee routers
CONS
- They’re Tuya, so the quality will depend on whether the whitelabel vendor is cutting corners. The ones I linked to have been stable so far.
- They use polling to get the energy monitoring data. In my case it’s not an issue because I’m not interested in millisecond precision - I just want to know the average load on my devices. Also, reporting interval can be changed in Z2MQTT.
- They initially had a bug where they would randomly report 0 consumption even when on. This has now been fixed in Z2MQTT and I haven’t seen a false reading since then.
I get that buying stuff (especially Tuya) from ali isn’t for everyone, but maybe the above mini-review will be helpful.
