  @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.

  Thanks for the reply. In short: Modbus TCP - MQTT: I'll probably just start off simple, by polling the Modbus server and exposing any changes as MQTT events. That way, I can get some feel with the setup and I can dig deeper later on. It's nice to know I can come back here for some assistance :) the LED strip: tried it the other day, and it just works; I hadn't taken the time before to properly connect them. DALI: looking forward to hearing more about it; had already seen the thread / python-dali before. Just good to see I'm on the right track here :)

  Hello @M-Musel, I think this is not possible. Digital inputs are connected directly to the GPIOs of RPi's processor. You might be able to control only Relays/Ai and 1Wire but the rest will not work - I am also not sure if there are any I2C devices in the Pi-Top so you would have to make sure the addresses would not colide with I2C devices on UniPi. You also cannot connect two UniPis together via the I2C

  Sure there is a solution for each industrial. We hope this is a challenging work to bring the automation in this industry.

  There are multiple solutions, see the list at wiki.unipi.technology Basically it depends if you want to use a free opensource solution (pidome,pimatic,…) or a completely different approach with proffesional solutions (Mervis) Both solutions are possible. But remember there are only 12digital inputs (14 if you make a custom cable). But eg with mervis you can hook multiple unipis together. Blinds are the same as lights, so yes. Depends on what AC you have, most of them has infrared remo tecontrol which should be used....

  hi all, yesterday i received the order (Thank you unipi) here is a background on my project: i am trying to setup a greenhouse to automate most of it using Unipi and jeedom. (i understand that jeedom already supported by a plugin) the greenhouse will have the following hardware: 2 X 340v exhaust fans 2x 240v 2000w water pumps 1x rollup side motor (to open the side for the ventilation) 8x light bulbs (only turned on during maintenance at night) The hardware i have is: raspberry pi 2 unipi boards unipi ssr unipi 1-wire hub uni pi 0-10v addon there is other components like weather station (outside and inside), some other sensors but i will add them after the basic setup is performed. my problem is wiring not the software as i have almost no experience with relays. any help will be great please.

  Hello, the DIs are max 24V DC only! Anything else will damage your UniPi. So you would need eg a external relay that will be switched by the 230V and will switch the 12/24V DC which will go to the digital input.

  Hello, I have made a mistake when committing the last update. The problem was that the custom.cext file was missing… Try to download the last master branch, it should be fixed. Regards, Tomas

  Hello David, you are correct. That's what I meant. Plus, as you said, you would need the 24V to go from the power supply to the relays of UniPi and to the button so you could switch the Teleruptors (which switch on the light) by the UniPi and by the button. Simple wiring diagram: 24V -> Button -> UniPi Digital Input + Teleruptor –> so the light switches every time you press the button plus UniPi knows that you switched it manually 24V -> UniPi Relay -> Teleruptors [attachment=0:1btsrd7c]20150209_120857_.jpg[/attachment:1btsrd7c] But you would have to deal with the digital input event after you turn on the relay on UniPi. Hope it helps. Best regards, Tomas
