Review: Great product and customizable and great support team - Great kit and easy to configure. In case, you connect 2 SHT20, make sure you update the access number so both devices are polled by the modbus master. I also contacted the support team which was very quick to answer and provide the answer. The support team also took into account that the documentation was only in chinese ( used Google translate) and will look at an english version which is very positive.
