Recently I have pushed to GitHub new example sketches for the Arduino like remote nodes. These include software modifications, that are needed for the changes made in gateway 2.x software. Hardware part of nodes is still the same for both wired(RS485) and radio(RFM69) nodes.
Changes include:
- Periodical ping to gateway. OHS 2.x gateway require a ping command from every registered node at lest one in an hour, or it is removed from node list.
- Arm home. This new functionality is added to authentication mechanism on node, precisely to iButton routine. It works as usual for arm away, that is a quick touch of iButton arms away or disarms the group. When arm home state is required, user needs hold the iButton in probe for more then 1 second. Disarm is same as for arm away, a quick touch only is enough.
- Authentication key is sent to gateway, and OK / Not OK sound is result of gateway accepting the packet with key. This does not mean that the key is valid and accepted, only that the gateway has received the key. On old node software, the OK / Not OK sound was result of iButton probe reading the iButton correctly or not.
- New method for CRC signature for RS485 packets.
Repositories with software for nodes compatible with OHS 2.x gateway has name starting with: OHS_2-node
I will add new node examples as I build them.
