SONOFF TH Elite Smart Temperature and Humidity Monitoring Switch

I am MUCH happier with this version! The most important feature is the improved electrical connections that will work for N. American wiring. Whoa. The LCD display gets high marks, and only needs a more reflective back surface to be more legible in dim light. The device itself requires a THS01 to be functional, and the THS01 is a reasonably accurate sensor.

All in all, high marks!

Din rail mount was a good idea. Happy so far with product. Still testing before I implement it to do something useful.
Have named it "laboratory" so I am able to use Alexa speaker by saying. "Alexa! What is the temperature of my laboratory" and it works but you need to use the Alexa APP to set Celsius or Fahrenheit.

Improvements over the old TH models
1) temperature connector is solid. In old ones I ended up messing about with them quite a lot.
2) wifi antenna improved. Previous one would occasionally disappear.
3) temperature logging now present. Should have been in past ones.
4) wire connectors much improved

There are only 2 negatives and it still deserves five stars;
1: No Earth/Ground
2. No wire grippers

Given the display is so nice it seems a mistake to put it in a box but that seems like the design. I have stuck it on the outside of a box, drilled holes for 4 wires and then glued them so they cannot be pulled. As it sits in a locked cupboard this seems safe although I would put it fully inside a box were there to be kids etc.

My first one stopped working on the wifi after 6 months so ordered new and seems ok now. Connect to home assistant easy but temperature reporting slow. Was able to open up and easily flash with tasmota. Works so well. Controlling my hot water cylinder so great to have a 20 amp relay to handle the load. Great price and seems good quality.

Much better than the previous version. It is worth the extra price and not necessarily because of the LCD, although it is also useful. Temperature and humidity measurement and control are more precise. Thank you.

After unpacking it I found that the LCD had a crack across it through the temperature display (underneath the covering glass layer).
After eventually installing it and figuring out the eWeLink app I got it to do what I want on my house heating boiler - turning on the pump above 35C and off under 20C.
I also had issues with installing, instructions, and gave feedback regarding the eWeLink app which I sent an email to [****] on Sun, 16 Oct 2022 17:23:07 +1100
which has not been responded to.
I am writing a review because of the recent email message prompting me to.

Great product and software is good too. Does exactly what is advertised. Setting up was fairly easy albeit it would help if I had known how easy it was with setting up the WIFI through the bluetooth. I would have started that way.
Loses a star because:
1. It loses WIFI connection once a week and has to be rebooted. (Access point 2 feet away)
2. Don’t know if the loss occurs because of software or hardware of device or if the access point loses connection to the rest of network, however even if it is a temporary network fault it should be able to reconnect when the network is back up. Don’t know if it tries to reconnect and isn’t able to or if it doesn’t try at all. (I have not tried with a static IP.)
I can’t comment on the actual accuracy and/or precision as I haven’t checked the calibration yet.

The device works ok, the user interface is intuitive and simple, but the soil moisture sensor makes measurements with very wide variations, quickly activating and deactivating the output, and to control a pumping unit, it would be affected. the error should be corrected by software so that the measurements are an average and abrupt jumps or false measurements are avoided

Package Configuration: It would be desirable to be able to mount this product in a standard US Electrical in-wall housing (rectangle), that would allow the user to place it INSIDE a wall not OUTSIDE it !! Only the display and the switch should be accessible to the user... all other wire connections should preferably be "hidden" in that electrical outlet box.

I am happy with this purchase.
They work well, and through the app I am informed of the temperature remotely.
The only thing, to comment that last week, the 4 THR316D that I have, lost Wi-Fi connectivity on the same day, at the same time it seems, although they depend on 3 different Wi-Fi routers.
I had to restart them to get them back online (off - on).
Now to wait for time to pass to confirm that it was just something specific.
That is why I give it 4 stars and not 5, which it surely deserves.
