NodeRED OPUS20

Node reads measurement channel from an OPUS20 device.

OPUS20 climate data logger devices werde manufactured by Lufft, Germany until 2023. However there are lots of OPUS20 data logger in the field. The power of the OPUS20 devices can be unlocked with a top-of-the-notch software support as NodeRED.

The OPUS20 data logger device highlights are:

• LAN-capable to enable comprehensive real-time monitoring networks
• Innovative housing design with various wall mounting options
• Can be powered through batteries or via a USB connection
• Features built-in sensors with the highest accuracy, making it indispensable for calibration laboratories
• Measures parameters such as temperature, relative humidity, and air pressure
• Utilizes advanced measurement technology: Temperature & air pressure with NTC, relative humidity with capacitive sensors

This OPUS20 NodeRED node

• provides easy access to OPUS20 devices over TCP/IP LAN
• provides access to all channels with live measurement valuesa (free version: 2 channels)
• can be chained to read multiple measurement values

However, it...

• does not yet support UDP broadcast to find OPUS20 in the network
• does not yet allow to read the internal data logger

Please drop us a note how you use your OPUS20 devices (see contact). Thx!
