frient Electricity Meter Interface | Wireless Consumption Readings | for Selected Devices | Battery-Powered | Consumer Electronics | Zigbee | Works with SmartThings and Homey

I've been using this for some months and found the readings both accurate and 'real-time'.I've just had a 'smart meter' installed and this product still works accurately and in a timely manner.Sadly, the Frient can't tell if the power is coming in or going out. So it will diligently give a reading, but I may be selling that power, not buying it.Shame, it's a neat unit and easy to install.

I use this energy meter with Home Assistant and the energy dashboard, the setup was easy and paired up in Zigbee2MQTT straight away.The range was a little poor so I did have to move a Zigbee smart socket closer to the meter so it could act as an extender, not the end of the world.My meter is outside in the usual whiteboard and installation was simple and easy.I've considered using an ESP8266 or Arduino based device to achieve something similar but for the price of this device, buying this device was a no-brainer.It's been running now for 48 days and the battery indicator is good (unfortunately not a % reading, either good or bad in Zigbee2MQTT).

Easy enough to setup - connected straightaway to my SmartThings hub but would not work with my Actaris LED meter. I even sent the first one back thinking it was faulty but the second one was identical in that it did not read the LED flashes.I checked everything - it was connected to the hub, it would send readings through if I flashed my LED cat toy at it, but as soon as I put it on the LED on the meter the readings just gradually fell to 0.

With the price of electricity going up and up I decided to get one of these to see our usage in combination with our solar panel system. Installation was very easy and was up and running in 5 mins. I know its spending money to save money but it does give a reassuring peace of mind to see our consumption from the grid fall to zero during the day most of the time depending on what we run.Paired up real easy using zigbeemqtt and I just had to input our tariff rate per unit to start seeing real £p readings. Nice bit of kit.I just wish I could buy the IR probe for it they mention so I can use it on the ISKRAEMECO ME382 meter attached to my solar pv.

I purchased this to monitor my Solar PV generation, replacing a similar, non Zigbee device.My Zigbee Gatway is the Conbee II - this paired perfectly.To start off with I was using DeCONZ, this paired straight away though didn't show up in the DeCONZ dashboard (but the total energy metric flowed straight into Home Assistant).After some research I decided to switch from DeCONZ to Zigbee2MQTT, this paired again straight away after resetting the Frient transmitter and shows nicely in the UI, as well as transmitting more metrics to Home Assistant than DeCONZ does. Likewise if you need to change the pulse rate from 1000imp/kWh you can do in Zigbee2MQTT easily)So I'd highly recommend this for energy monitoring, it reconciles perfectly with the generation meter.

With energy prices going crazy, I wanted to have a way of monitoring our energy use. I use this with Home Assistant and it works well. It uses a photo diode to measure the LED flashes on the meter and it's been very accurate, matching up with our bills. It runs on two AA batteries and these seem to last a very long time. Our meter has finally been upgraded to SMETS2, but before this happened this gave me more accurate readings than waiting for the monthly bill. Still a useful device to have, even if you have a SMETS2 meter as you can set up alerts in Home Assistant, if your energy use spikes, for instance.

I've got this up and running with zigbee2mqtt and home assistant, it turns out that my zigbee2mqtt install was a bit old, so didn't recognise the device, after an upgrade it's all working fine. Seems accurate enough but I've only had it running a little while will do actual comparison tests later.One warning with the LEDs on the device, it paired to my setup so fast that I didn't see the LEDs indicating it was searching for the zigbee network. I was also in a dark room and still found it difficult to see the LEDs when they actually lit up. I only spotted the LEDs after a round of testing the supplied batteries with a meter and then holding the reset button. I couldn't see that any LED stayed on to indicate that the device was active and working.

This Frient unit is actually a rebranded Develco ZHEMI101.No problems installing this on a Landis & Gyr E470 meter. Just need to pull off the velcro ring from the included sensor and stick it to the front of the meter over the flashing LED. I added a short screw to the wood board in the meter enclosure and hung this unit on it. Good LQI even though it is in a box on the outside of the house.I connected it to Home Assistant using Zigbee2MQTT. My meter is 1000 pulses/kWh so I used all the defaults. If yours is something else like 4000 pulses/kWh then you'll need to edit the config.I compared it against the in-home display unit from the electricity company and readings were accurate within +/- 6W. This Zigbee monitor updates much faster than the in-home display so any larger discrepancy is usually due to update lag on the IHD.

I am using it with Homey and once connected (a bit of a hassle) it works fine. Updates roughly every 15s.IMO it is just a bit on the expensive side for what it offers.

Per quello che riguarda la parte tecnica non posso dire assolutamente nulla in quanto funziona tutto correttamente, l'ho collegato velocemente al mio router zigbee e assistente casalingo (conbee II + raspberry + ZHA + home assistant) e vedo immediatamente i dati. Il problema è dato dal fatto che avendo un impianto fotovoltaico e vendendo l'eccesso al GSE il mio contatore è bidirezionale, questo fa si che venga segnalato come consumo sia il reale consumo di casa (corretto) che la parte ceduta alla rete nel momento di sovraproduzione (errato), alterando completamente i dati letti. Inoltre il fotovoltaico nei momenti di sovraproduzione introduce errori sul contatore che vengono letti come dei picchi difficilmente filtrabili. Credo che lo restituirò e passerò ad una soluzione con anelli amperometrici forse più adatta a chi ha un impianto fotovoltaico collegato alla rete.TLDR: il problema non è lo strumento, ma il led RA del contatore bidirezionale che non segnala solo il consumo, ma anche la produzione scazzando completamente il calcolo del consumo reale. Ci verrebbe un qualcosa che segnali se sei in consumo o in cessione alla rete.

I have my electrical service point down in a storage room in one corner of the basement. We have concrete floors between all floors, and my Sonoff ZigBee 3.0 dongle on the top floor two floors up (by the staricase, though) get reliable metrics from the Frient energy meter to my Raspberry Pi 4B running Home Assistant with zigbee2mqtt.I can't speak for the accuracy, but installation was really simple. Insert batteries, attach the sensor with a supplied self-adhesive velcro ring over the LED on the service point.I can now see clearly in Home Assistant when the power curve indicates the heater kicking in or the stove is being used - as well as daily energy usage.Recommend.

Das Develco ZHEMI 101 ist sehr vielseitig konfigurierbar, und lässt sich dementsprechend vielseitig einsetzen. Käufer sollten sich jedoch bewusst sein dass die Konfigurationsmöglichkeiten nur über das setzen von Vendor-specific Zigbee Attributes zugänglich sind. Man braucht also eine Möglichkeit um Zigbee Kommandos zum schreiben dieser Attribute zum Gerät zu senden. U.a. mit zigbee2mqtt geht das z.B. ganz gut. Für den extremen Selbermacher kann man sowas z.B. auch mit einem XBEE USB Stick hinbekommen.Ich selber nutze zwei dieser Geräte; eines mit der mitgelieferten optischen Sonde; diese funktioniert auch mit dem IR puls meines Stromzählers; und ein weiteres für meinen mechanischen Gaszähler, der mit einem Reed-Schalter ausgerüstet ist. Mann muss nur den 4-poligen 3.5mm Stecker wie abgebildet mit einem Widerstand an den Reed-Kontakt anschließen.Gut zu wissen ist übrigens auch dass das gerät über einen 5.5x2.1mm Hohlstecker extern mit Spannung (4.5V) versorgt werden kann.

Enfin une solution pour connecter le Linky sans être électricien. Facile à installer. Mesure précise vs relevé du fournisseur d'électricité.Intégration dans home assistant très facile.L'outil parfait pour suivre sa consommation d'énergie.Packaging de très bonne qualité.Le capteur optique est assez epais (4/5 cm) . Attention si le Linky est dans un coffre.Marque à recommander. Protocole zigbee.
