Developer Programs Writing Device Types

Hi @Itati
Thanks for your reply.

I think the answer to this question should be Yes, it just affects the operation of routines in case the supported values ​​sent by the devices are valid and if they are incorrect.

I think for some users, it uses some Tuya devices TS0201, it will malfunction and will not be able to perform certain routines, but it is not a smartthings problem, it is a Tuya problem.

Hello @Mariano_Colmenarejo, I was just wondering if you managed to fix your devices? I’m experiencing the exact same problem you mentioned here with a couple of TS0201 sensors that have a range limit that doesn’t make sense (31.3-31.8), so I can’t use them for any automation. Maybe you figured it out. Thanks!

Tuya misunderstood what the attributes Min Measured Value and Max Measured Value are really for.

The standard says:

The Min/Max Measured Value information attribute set contains the minimum/maximum value that the remote sensor is capable to measure.

But they are storing the min/max temperature the device ever measured.

SmartThings drivers use these attributes to determine and set the range that can be used in routines, for example.

To expand the range, you can put your sensor in a freezer for half an hour and heat it up with a hair dryer afterwards…

Edit: just realized that this was already explained in this thread.

Hola Alex,

Added to these driver versions

You need install one of those drivers
uninstall devices and reinstall with driver version installed to perform a correct device configuration

Te deseo Feliz Navidad y un prospero año Nuevo

Muchas gracias @Mariano_Colmenarejo!

This worked perfectly and I can now use the temperature range.

Now I just have to fix an issue of constant disconnection of a couple of sensors, but I suspect it’s because of a wifi repeater affecting the zigbee.

And same to you, have a very good end of the year and an even better new year! Abrazo!!
