Looking for a zigbee power meter plug without a switch (lemmy.ml)

As the title says, I'm looking for a plug that can measure power consumption, but does not even have a relay to power it on or off. I want it always to be on. The reason is that I'm tired of my smart plugs randomly turning off for no reason, even after I've updated them to the latest firmware version. Heck, I even have an automation in Home Assistant that turns them on again when it happens. I don't even know if what I'm looking for does even exist. I've been looking around and haven't found anything like it. If any of you fine folks know, please shout!

Depending on your level of technical skill and willingness to risk crack things open, you can flash most Tasmota type devices with esphome and hard code it to be always on. This would go along way to eliminating software as the problem. I have done this with meters attached to my washing machine and dishwasher.

Also, the boards are also relatively simple and it is likely (although there are lots of variants) that you could remove the relay completely and bridge across the terminals. I wouldn’t plug my electric car into it (10A sustained) but you could put a led lamp through it without without much risk.

Disclaimer - I am a hobbyist, not an electrician. YMMV, keep a fire extinguisher nearby, yadda yadda

That's a good solution, but ESPHome is for WiFi, and my plugs are Zigbee. On the other hand, bridging the relay is not a bad idea 🤔 Thanks!
