After round about one year of successfull usage i want to share my little Hörmann garage door project with you.
I own a Hörmann garage door driven by a Supramatic E3 and i searched a way to integrate it into Home Assistant.
If one searches the internet one will find solutions which use a Hörmann UAP1 and control the UAP1 via mosfets or relais.
Inspired by Bouni’s blog i thought there must be a way of controlling the Supramatic without using a UAP1. After some try and error i found a solution which eliminates the usage of the UAP1.
I’ve designed a little PCB which connects to the Supramatic E3 via the Hörmann bus on the one side and to Home Assistant via WLAN/MQTT on the other side. On my PCB i have two controllers. One PIC16F15324 which emulates the UAP1 on the Hörmann bus. One ESP8266 to connect to Home Assistant. I decided to go for a two controller solution because the Hörmann-Bus has some contrains (response timing, LIN sync break) which, i think, are easier to implement in a second controller than in the ESP8266.
The PCB is powered directly from the Hörmann-Bus via an SMPS. Via the ribbon cable an BME280 is connected to the ESP8266.
I have a Lineamatic motor for the outside gate and a Supramatic for the garage door. They should both work the same. I would be interested in buying the solution. Have you thought of a price for the board ?
I am thinking of having this board made in China but minimum batch is 5. Cost would be ~$60 each fully assembled with all components (ie $50 + duty/VAT for getting it into the UK). You’ll then have to add shipping from UK and your local tax.
Still may be a cheaper option than buying parts separately or using breakout boards.
If there is sufficient interest at these prices I will get this ordered, so please let me know.
for which doors will this PCB work? I have a supramatic P3 - which does have an BUS connector.
And will I be able to see of the door is actually open or closed within HA?
I can only confirm that it works with a Supramatic E3, but i think it will work with other doors as well.
The door state (open, closed, venting, opening, closing, error) is reported to HA. Sensor “Garagentor” in my dashboard card.
Hi everyone, I’m also interested by this board. @BotchedIt did you succeed to order them already? If yes, can you describe what services you used?
Thanks!
So I had 5 units made in China and have mine working, see pics (yes I’m up north and it’s crap weather here).
Both electronics design and software were prepared very well by Stephan and I had little or no issues in manufacturing, flashing the pic/ESP or setting it up in HA.
I have sold several to you lovely people on here, I have 1 unit left to sell, cost ~£50 incl shipping (depending where you live), first come first serve, PM me.
