LoRaTLS Trinkwasserzähler

Trio develops innovative digital water meter for the German market with encrypted LoRaWAN

Kams­trup, GELSENWASSER AG and PHYSEC GmbH have joi­ned for­ces to deve­lop a digi­tal water meter with LoRa­WAN com­mu­ni­ca­ti­on technology.
On Decem­ber 22, 2020, a con­tract was signed by Kams­trup, Danish pro­vi­der of sys­tem solu­ti­ons for intel­li­gent ener­gy and water mete­ring, GELSENWASSER AG, one of Germany’s lar­gest water uti­li­ties, and PHYSEC GmbH, a spe­cia­list for inno­va­ti­ve secu­ri­ty and con­nec­ti­vi­ty con­cepts. In 2021, the com­pa­nies will joint­ly launch an elec­tro­nic water meter with LoRa TLS com­mu­ni­ca­ti­on modu­le on the Ger­man mar­ket. PHYSEC has alrea­dy deve­lo­ped the LoRa TLS com­mu­ni­ca­ti­on tech­no­lo­gy tog­e­ther with Gelsenwasser.

Tes­ting the com­mu­ni­ca­ti­on modu­le thoroughly
The LoRa­WAN com­mu­ni­ca­ti­on tech­no­lo­gy is being tes­ted in prac­ti­ce in the city of Gel­sen­kir­chen and is expec­ted to cover around 400 meters by the end of 2020. So far, com­mu­ni­ca­ti­on in this test envi­ron­ment is done via an exter­nal box moun­ted on the digi­tal water meter, which is manu­fac­tu­red by eBZ, a Gel­sen­was­ser asso­cia­ted com­pa­ny. In the future, this box will be repla­ced by a TLS-over-LoRa­WAN com­mu­ni­ca­ti­on modu­le inte­gra­ted into the water meter. LoRa­WAN is a Low Power Wide Area Net­work spe­ci­fi­ca­ti­on for wire­less bat­te­ry-powe­red sys­tems in a regio­nal, natio­nal or even glo­bal net­work. LoRa­WAN tar­gets the most important requi­re­ments of Inter­net of Things (IoT), such as bidi­rec­tio­n­al com­mu­ni­ca­ti­on, loca­liz­a­ti­on and mobi­li­ty of services.

The IoTree secu­ri­ty midd­le­wa­re pro­vi­ded by PHYSEC app­lies the TLS pro­to­col over the LoRa­WAN radio pro­to­col to ensu­re sta­te-of-the-art end-to-end secu­ri­ty at the hig­hest secu­ri­ty level and com­pli­ant with BSI spe­ci­fi­ca­ti­ons. The sys­tems cur­r­ent­ly avail­ab­le on the mar­ket ope­ra­te on the basis of the spe­ci­fied secu­ri­ty mecha­nisms of the LoRA­WAN pro­to­col, which do not meet the­se requi­re­ments. The paten­ted solu­ti­on enab­les secu­re com­mu­ni­ca­ti­on in the Inter­net of Things for ope­ra­tors of cri­ti­cal infra­st­ruc­tures, uti­li­ties and water providers.

The very first digi­tal meters will be deploy­ed in 2022
The first elec­tro­nic water meters with TLS-over-LoRa­WAN com­mu­ni­ca­ti­on tech­no­lo­gy will be avail­ab­le next year (2021). Gel­sen­was­ser plans to deploy 25,000 units by ear­ly 2022

With its pro­duct IoTree, PHYSEC pro­vi­des a matu­re IoT plat­form with a spe­cial focus on the secu­ri­ty of cyber-phy­si­cal app­li­ca­ti­ons. In dif­fe­ren­tia­ti­on to exis­ting plat­forms, IoTree offers all com­pon­ents from the secu­ri­ty of the end device (mani­pu­la­ti­on detec­tion) over the secu­re radio com­mu­ni­ca­ti­on (LPWAN) up to the app­li­ca­ti­on. The plat­form has open inter­faces that for­ward data to value-added ser­vices. The LoRa­WAN tech­no­lo­gy modu­le enab­les device manu­fac­tu­rers to secu­re­ly digi­ti­ze pro­ducts, and uti­li­ties are sup­por­ted from net­work set­up to roll-out. The inno­va­ti­ve secu­ri­ty and con­nec­ti­vi­ty con­cepts enab­le the imple­men­ta­ti­on of digi­tal busi­ness models with the hig­hest IT secu­ri­ty as well as ease of use at the same time, con­tri­bu­ting to the digi­tal auto­no­my of users. PHYSEC has recei­ved nume­rous awards for its pro­ducts and busi­ness model.

About Gel­sen­was­ser
All life comes from water — that’s how Gel­sen­was­ser came into being! Foun­ded in 1887 in the Ruhr area to sup­ply the coal and steel indus­try and the peop­le of the regi­on with water, we are now one of Germany’s lar­gest water uti­li­ties. Resour­ce con­ser­va­ti­on is very important to us. Our logo has shown this ori­en­ta­ti­on for over 40 years: The blue river in a green land­s­cape stands for sus­tainab­le, respon­si­ble resour­ce manage­ment — this app­lies to all busi­ness are­as. Infra­st­ruc­tu­re and uti­li­ties are our focus are­as: from water and sewa­ge to ener­gy (gas, electri­ci­ty, wind, PV, heat) and digi­tal. We also share our know-how with our part­ners as ser­vices or in joint pro­jects. Always with a view to the spe­ci­fic needs on site in order to achie­ve via­ble, cost-effec­ti­ve solu­ti­ons. This also inclu­des the part­ners­hip with Kams­trup and Phy­sec — for inno­va­ti­ve, safe and respon­si­ble digi­ta­liz­a­ti­on in drin­king water supply.

About Kams­trup
Kams­trup is one of the world’s lea­ding pro­vi­ders of sys­tem solu­ti­ons for smart ener­gy and water mete­ring. Our solu­ti­ons are used by uti­li­ties and pro­per­ty mana­gers around the world, pro­vi­ding reli­able and cost-effec­ti­ve mete­ring. By under­stan­ding the cus­to­mers’ chal­len­ges upfront, we can help opti­mi­ze busi­ness pro­ces­ses and inspi­re smar­ter as well as more respon­si­ble solu­ti­ons. The port­fo­lio inclu­des con­sump­ti­on meters, remo­te rea­ding sys­tems, hos­ting and ser­vice, as well as ana­ly­tics and smart grid app­li­ca­ti­ons. All pro­ducts are manu­fac­tu­red in Den­mark and meet the hig­hest envi­ron­men­tal and qua­li­ty certifications.

Solutions for the modern public utility industry

With our solu­ti­on for the effi­ci­ent remo­te rea­dout of water- and electri­ci­ty meters, PHYSEC GmbH was pre­sent at the ‘e‑world ener­gy & water’ in Essen: LoRa®TLS enab­les the instal­la­ti­on of secu­re and encryp­ted radio com­mu­ni­ca­ti­ons over long distances.

As a holistic solu­ti­on it is the­re­fo­re espe­cial­ly rele­vant for public uti­li­ties like muni­ci­pal uti­li­ties. Addi­tio­nal­ly, it is an inte­gral part when it comes to smart city concepts.

The pro­ject is con­duc­ted tog­e­ther with our part­ner Gel­sen­was­ser AG and was deve­lo­ped one year ago.
