Sorry, working 7 days a week so not a lot of time to spend on Homey… At the moment it looks like writing in test mode is not working at all. Reading bits is working quite well, maybe a bit slow but that can be the issue of Homey :). Already a few weeks it’s reading the state of different door and wi…

Can you show me some examples if you have some time? I wonder whap happens in your case. It just reads INT16, addes the bit with a bitmask and writes back the INT16. Or is it a 2 register field? Shouln’d be one if using Bits :thinking:

If for example the wired MODBUS TCP/IP connection is still alive, but there is for a certain period no connection with the internet (cloud). Will the modbus data be stored on the Homey pro device, and does it send the data to the cloud once the internet connection is back? And how much data can be …

The app just sends the data if the flow card is processed. If there is an error, the flow card errors (error output at the bottom of the card). There is no queueing.

As an alternative to data queuing; might it perhaps an idea to install and use the “micro web server” on my local network? Theoretically this than grant’s that the modbus data flow continues even though the internet connection is lost? And use port forwarding to access remotely the “micro web server…
