@martin-kudláček said in Another home automation project:

our din rail mounted relay - and connect it to DO or RO. Awkward, but it works.

In most of my projects i use external relays to extend the life of embedded hardware relays, so it's not that awkward. I use mostly relays with coil voltage 230 V AC with UniPi 1.1 but now with the shared COM port and neuron power suply, i'll go with coil voltage 24 V DC.

Hello,

then you also need to tell the system to connect to the network:

wpa_supplicant -Dwext -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf

You might also want to automatically reconnect to the network, this can be done using the provided script:

Go to /etc/ifplugd/action.d/ and rename the ifupdown file to ifupdown.original

Then do: cp /etc/wpa_supplicant/ifupdown.sh ./ifupdown

I would like to use the two analog inputs to measure - monitor ac current of a heat pump. Do you have any suggestions of how to do it or what hardware can i use to make it work ?

Thanks !

Hello,

thanks for the tip. We are already prototyping a few new 1wire sensors including this one

@blacksoll Those products are only temperature sensors. If you are looking for humidity sensor, take a look at our offer of the Sedtronic products: https://www.unipi.technology/sedtronic-1-wire-sensor-p67?categoryId=3

Here is an example of the flow with Tomas flow as well.
You must edit the nodes to match with your installation. My evok listens at port 8181 so you must edit that also edit make http responce node with your own ip installation and the nodes for temp sensors…...........

Select all and import it to nodered ! After edit, visit http:// your_unipi_ip:1880/temp and see the temperature page. You must wait a few seconds until evok reads the sensors. Just refresh the page.

I would really like to help you out with the domoticz implementation but I still do not have enough time for that… But domoticz is a really interresting project which I think should have a full support for UniPi.

Hello,

the Pidome looks interresting. I will take a closer look at it.

You shall have no problems at all. The UART pins are wired out directly to one the RJ11 connectors of UniPi.
