Hi, I am trying to integrate my LG hot water heat pump with the LG ThinkQ app, unfortunately without success. I always get the error message: Cannot read properties of null (reading length) Can someone here help me where the error lies. I am logged in to my LG ThinkQ account. The original LG ThinkQ app also works without any problems. Greetings from Hamburg Tim ---

Hi Tim, Please be more specific šŸ˜‰ > [@Tim\_Nagel](#): > > I am logged in to my LG ThinkQ account Where, @ Homey or smartphone? > [@Tim\_Nagel](#): > > The original LG ThinkQ app also works Nice. What is that? The ā€œofficialā€ Homey app store app? Smartphone app? Martin Verbeekā€™s Homey app? Which Homey model do you own? Which LG Thinq Homey app version is this about?

Hello Peter, 1. I had logged into my LG ThinQ acount on my iPad from there I could directly access my LG domestic hot water heat pump THERMA V 200 liter dual inverter R134A hot water heat pump without any problems. 2. installed the app: LG ThinQ Smart living starts with LG ThinQ by Martin Verbeek on my Homey Pro. Is there another one for the LG domestic hot water heat pump? 3. the version is 3.1.17 4. I have tested it with the app on the IPhone, IPad and Windows PC, unfortunately always the same result. 5. while searching the forum I found a small solution to my problem. I have been using Homee for the last few years and have just switched to Homey. In general, I like Homey very much. Best regards Tim ---

I only know thereā€™s multiple LG apps, hence my question to specify. Concerning Martinā€™s LG app, itā€™s best to ask your questions in his LG Thinq app topics I linked to, but this oneā€™s in Dutch: > [@\[APP\]\[Pro\] LG ThinQ integratie](https://community.homey.app/t/app-pro-lg-thinq-integratie/82324): > > Op dit moment support voor ThinQ V2 en V1 ACā€™s, V2 Heatpump Boiler, V2 Wasmachine V1 in test, V2 Droger V1 in test, V1 en V2 Fridge, V2 AWHP Ik bezit zelf deze apparaten niet en doe het in samenwerking met eigenaren die zo vriendelijk zijn om de apparaten te sharen in de LG ThinQ app. Kort door de bocht kan ik dus niet alle mogelijkheden testen en zal er in het begin best wel wat fout gaan.

Hallo Peter, Hartelijk dank voor je hulp, ik heb de fout gevonden. Ik had een fout gemaakt met de toegangsgegevens. Ik heb dit gecorrigeerd en nu werkt het. Groeten Tim
