Non-Battery powered temperature and humidity sensors

Thanks for confirming. In never did test it for accuracy. Although, I've got a fair bit of experience with how inaccurate many of them are over a given range, so I don't expect much from anything that doesn't have mercury in it :wink:

It's concerning when are driving HVAC off it, if I'm out 2-3 degrees or 5-10% humidity (both of which I've seen with those sensors) it completely changes how the house feels..

I see. I'm an Ecobee user, so I'm relying on their remote sensors. I'm assuming they are accurate. Haven't really tried to verify. We don't have A/C, and for heating they seem good enough. The house stays much more evenly heated then when we just had a single programmable thermostat downstairs.

I get I'm straying here from the "Non-Battery powered...", but I felt obligated to post this as I mentioned it earlier in the thread. I was able to recalibrate the radio signal and get my tags working again.

Here is a graph of an uncalibrated WirelessTag along with my Thermostat. There is a 2-3 minute delay as the path is WirelessTag -> Cloud -> SmartThings Hub -> Hublink -> HE. Still it's pretty impressive. It seems to be tracking within .4 of a degree F and changes within 3-4 minutes of the thermostat. I can tighten up the delay but that will hammer the CR2034 battery in the tag. If enough people get interested, maybe it'll help motivate a driver rewrite to work directly with HE.

The green line is my thermostat that only changes in .5 degree increments. The orange line is my Guest Room Wirelesstag.

Got my Aeotec MultiSensor 6 today. Plugged it in and got it going with @csteele's driver. Seems pretty stable so far and meets the requirements of being plugged in.

I'm experimenting with 'hiding advanced options' once they've been set in that driver.

as was discussed in that thread.

Seems like a good idea.

I found a somewhat hidden place for mine since LUX/Motion/IR are not my concern. Significant Other somewhat approves.

Nice spot. Is that cable long enough that you can tuck it under the cabinet?

any updates on this issue.. don't like the aeotec as had report spamming issues with them in the past..

have dehumidifiers in the basement and would like a usb powered multisensor or temp humidity that i dont have to worry about the battery going dead the months the house is empty.. I have switches on the dehumidifier i can turn off if need be..

thanks

@kahn-hubitat I have converted many battery powered motion and temp/humidity sensors to mains power via this method:

These have worked out very well. Only issue is a one motion sensor goes into pairing mode if power is cut and I have to rejoin the sensor each time. I ended up plugging the USB adapter into a smart plug so I can toggle it while starting the Zigbee join process. I dont understand why this one sensor does this because 5 others do not exhibit this behavior.

These are the temp/humidity sensors I am using:
