Hello there, I’m currently developing a Homey App that is able to communicate with the Marstek Venus Battery over LAN (WiFi) using local API capabilities and using Marstek Cloud. It uses UDP communication or a cloud webservice to poll data from the battery and add devices with properties into Homey…

After a mode change command is transmitted, the Homey App waits 10 seconds for an expected reply. If the reply does not match the expected format, it retries for a maximum of 5 tries. Then it throws and error to Homey (your Red Card situation). Can you send the diagnostics report after you’ve encou…

I’ve implemented a 5-second delay between the batteries. While it may not solve the issue, it won’t cause any harm. Currently, switching modes twice on both batteries triggers a ‘red card’ error, even though both batteries actually updated their modes correctly. Marstek Energy Storage v1.1.2 M…
