OHS is open source based burglar alarm and automation platform. It can work as new alarm gateway, or it can replace your old alarm panel. OHS can use any wired 12V sensor, PIR, smoke or reed switch. It has Web interface that is used to set it up. OHS has GSM modem that is able to send SMS or page you. It has radio interface for environmental sensors. OHS is self-contained, it does not need any cloud service, only optional SMTP server for emails, or MQTT server to publish collected sensor data.
I will prepare the cost calculation and than it should be ready. One more thing I have on mind is to replace STM32F407 by STM32F437. It should be pin to pin compatible, also it is faster and it is around 2 Eur more expensive. But it has HW CRYPTO unit and 64KB more RAM. Meaning it can in future do SSL/TLS and possibly other things. What do you think? Also what region are you from? Would you be interested in GSM/LTE module? Adam
Thanks for so qick reply. I am located in UK. Realy interesting product due sim (GSM/LTE)- ethernet port on board. (replace for satel 8 zone system) Looking in to build two devices security/ system-home /automation- DVR cctv /picture capture based on OHS 2.0.4/ Raspberry Pi 4. better performace sounds good especialy with crypto unit. Two evros on a price with extra performance - wider range programing ability is great idea to have. Hope to be able order soon your updated product.
Do you mean new gateway 2? Yes, hardware is compatible, only you need to upload new example sketch. It has new functionalities, like arm home/away. Same for radio nodes, only new sketch is needed.
Hello, there are lables on the PCB, and BOM-OHS-gateway-17C.csv in download section on my Google drive. D12 is 3W 3V6 or 3V9 zener diode, used as extra protection, it will work without it. Just last barrier to protect the 3V3 rail from spikes. If you have other questions, please post in forum.
Hello I am wondering when OHS 2.0.4 version will be ready for public to buy?

I put the new GW to catalog along with options for modem and radio.
DeleteGreat Thanks Plese let me know by sheeping as Ive made payment over paypal.
ReplyDeleteAlso please place your latest firmware on it thanks.
Hello, thanks for order. I see it. It usually takes 2-3 weeks to prepare and complete the order.
DeleteFor firmware, sure I'll put the latest.
Is this compatible with existing RS485 nodes?

What is the voltage of diode D12? Is possible to share component placement plan?
ReplyDelete...version 1.7C
