TH16 Auto temperature setting resolution


I am using the TH16 as a thermostat for my apartment's room temperature, and has proven very handy for this. I can now set a different temperature for the nighttime or periods when i am away.

The only problem is the way you set upper and lower limits.

I like to have the temperature set at a steady 21 degrees celsius, so i put in 21 degrees as both the lower and upper area in ewelink.

The only problem is that this setting means that it only kicks in at temperatures lower than 21.0 degrees, and switches off at temperatures higher than 21.0 degrees.

This means that it kicks in only at 20.0 degrees, which i feels is to cold, and switches off at 22.0 degrees which i find to be too hot.

Is it possible to maybe add a decimal point to the values than can be set?

Even if your sensor has a resolution of 0.5 degrees, you can still set up ewelink so that the difference in temperature equates to just 0.5 or 1 degrees.

Hi, I have the same issue, and it would be great to add decimals to temperature. Thanks

Or be able to set in F and not C

yup, need F and finer resolutions.

Same problem. Adding decimals would be nice.

Same issue with my aquarium. I need more accuracy, because 2°C delta is too big

I have new firmware now, 2.6.0 and i am now able to set the temperature in decimals, for instance:

higher than 20° is off

lower than 19.9° is on

But it just doesn't work that way, the Sonoff still waits till it becomes 21° before turning off.

So, idea looks ok to me but for some reason it doesn't work as expected/wanted

İt is very simple for itead but after products sales support is 0

Only 1ºC accuracy? 


I'm sure this sensor can handle decimals, even if not so accurate. Please add this option.

Also, if you don't display the decimals, your accuracy is no more the one that is written on the brochure but much bigger!!

Bu işi yapmayacaklar sanırım. Bir daha bu üründen almayacağım. Satış sonrası destek sıfır. Kodda 2 satır değiştirecekler onu da yapmıyorlar.

I guess we need a way to set the hysteresis, that is the difference of temperature the TH would allow before trying to adjust it.

Sonoff must do his job on the software side. I have flashed my TH10 with Tasmota firmware, and there you can see the temperature in 0,1°C steps. And it reacts very fast to room temperature changes. By default it reads every 300 sec, but you can change this value to whatever you want. And what about the scenarios on the app? Do they really want to do a good job? Or they only want to sell hardware? And that they're doing it very well.
