DSMR stopped updating after new smart meter

[semafoor]

Hi there,

I recently had my smart meter replaced. Before everything was running really (!) smoothly with HA. After the new smart meter the DSMR integration stopped updating.

I tried restarting HA. Updating. Removing the HUB. Renaming entities. No success sadly.

When i remove the hub and add it again, it looks like I get a fresh set of readings, but no updates.

I can read the smart meter (DSMR 5) with the terminal. After setting the baudrate to 115200 with

stty -F /dev/ttyUSB0 raw 115200 cs8 -cstopb -parenb -ixon -ixoff

It posts the telegram messages. This also works with

cat usb-FTDI_FT232R_USB_UART_AI1TO3PX-if00-port0

When I remove the HUB and re-add it, I first need to change the baudrate in the terminal te receive the P1-telegram messages again. However changing the baudrate does not help updating the measurements with in HA.

Downloading the diagnostics from within HA does however result in changing readings per measurement in the different diagnostic JSONs.

Are there any hints I could look into to fix this matter?

Thanks!

After a meter replacement it takes some time (sometimes 48 hours) for your energy provider to setup your new meter. In your second screenshot you see “unit” is empty. That one should be filled, which it will after the setup. So just relax and wait until data is received correctly. It took a couple of hours until the data was correct again at my place.

I dont think thats it. The empty unit refers to the current tariff. Which is 1 for low and 2 for high. The tariff has no unit.
