@tin-androić What do you see when you try to re-attach the unipi lite again?

@viljar-kaarde Fixed in the update of the app.

@pablofsmelo did you figured it out?

This is a very rare issue with stuck SPI line, let us know on email or phone when/if this happens next time so we can see it.

@csacher Do you mean the read period or what?

It will fit OK, however it will complain (just a warning, not an error) about old device prototypes, because newer version v2.1 are already available in the IDE. Prototypes v2.0 will be marked as obsolete in the next release so it will be needed to update to v2.1 later.

Hello @pascal37,

thanks for pointing this out. We have missed the config file responsible for static mapping of the USB ports. Its now part of the unipi-common package in version 1.2.15.test.20191129155215 so you can install it by "apt update && apt install unipi-common=1.2.15.test.20191129155215" or get a fixed OS image version 2.2.0.20 from our knowledge base.

@derinex The most important changes is described in the newsletter or also in the news on our pages https://www.unipi.technology/news/introducing-the-new-mervis-ide-2-2-0-295

All changes are inlcluded in the builtin changelog of Mervis.

@wavoigt We have tested HMI terminals from weintek like this one https://www.unipi.technology/weintek-mt8051ip-p198?categoryId=29 via Modbus RTU (RS485). Works well but the SW setup is a bit complicated.

Mervis has recently gained BACnet server support so you can connect higher verions of Weintek displays which support BACnet with Neuron or Axon via BACnet/IP

Alternatively Mervis has a web based HMI so you can also use this with any web browser while on the same IP network.

@r3sist thanks for clarification.

The best would be to setup a HMI terminal like this one https://www.unipi.technology/weintek-mt8051ip-p198?categoryId=29

Hooking buttons to DIs would be OK, but you would have to figure out the display since Neuron do not have native support for HDMI or I2C displays.
