Owon THS317-ET remote temperature sensor test

Given the rainy weather at the moment, I wanted to stay in the same state of mind by presenting to you today a temperature and fluid sensor with remote probe Owon THS317-ET, it stands out from the other products in the same range , but it costs 20€ so will it interest you in any case it is one of the top sellers on domadoo, whom I would like to thank for graciously providing me with this module.

OWON - REMOTE TEMPERATURE PROBE ON ZIGBEE CABLE

The THS-317-ET module makes it possible to accurately measure the temperature of a space, a material or a liquid.

Owon manufactures a product range called PIR323 and the THS317 sensor is one of them, this PIR323 range includes 6 models and all use the same box but do not have the same functions. This is why this box has a PIR lens and holes on both sides but are not used in the THS317-ET, this one is only a remote temperature sensor, but in the range you find PIR sensors, temperature and humidity sensors and even a vibration sensor.

Download the technical characteristics notice a little further down, you will understand better what I wanted to tell you.

The box is of good quality, I still regret that the connecting wire of the temperature sensor is not more reinforced, especially since it is a temperature sensor for external use.

I tested it in the water and the feedback seems correct.

Under the hood is a relatively simple printed circuit and Owon has equipped its module with a Zigbee Tuya ZS3L chip. I would have preferred a CC253X chip here too in order to be able to modify the Firmware more easily, but currently all manufacturers are turning to Tuya to equip Zigbee modules, certainly it is a question of price.

The dimensions of the modules are relatively imposing, more than 6cm on each side, which is enormous for this type of product.

Inclusion

The inclusion is done without worries in ** Zigbee2mqtt, ZHA and Jeedom ** however I did not respect the instructions which ** tell me about red and green LED ** after 10 seconds of pressing the reset button . I have never been able to see Led Rouge.

Certainly that it is activated in case of inclusion errors, in short it is not so serious at this stage.

Zigbee2mqtt

everything went well the temperature increase did not happen immediately after the integration, apart from that no problems encountered.

ZHA integration

On the side of ZHA no worries either, the temperature rise was done correctly, you can see that the precision counts one digit after the decimal point, I regret a precision which could have been made two digits after the decimal point but here I quibble.

Jeedom integration

Finally under jeedom, an integration there also correct, in short, only happiness.

Personally I’ll put ZHA in mind for this integration, the fact that it’s integrated directly into Homeassistant is a plus, and yes, if you haven’t understood it yet, it’s my favorite home automation system.
