@aren I have added your device fingerprint as "Tuya / Neo NAS-WR01" in version 1.1.2 of "Tuya Zigbee Metering Plug" driver. You can update it from HPM or directly from this link.
Please hit the 'Configure' button after updating the driver. Also, make sure your device is actually using this driver:
If after updating and Configuring again the On/Off commands and power/energy readings still do not work, please re-pair the device again to HE hub. I think that repairing again should not be needed, as this is a mains powered zigbee device and the configuration commands should be accepted almost immediately.
@aaiyar The problem seems to be that Markus's driver has the same inClusers and outClusters list, and his driver is selected automatically during the pairing process (probably because this driver was installed earlier than the Tuya driber). Now when this specific device inClusters, outClusters, mode, and manufacturer matches exactly the fingerprint in my driver it should be selected automatically when paired, instead of partially matching Markus driver.
