At H60 startup, it will try to connect to the MQTT Broker (server).
If connection failed, it will retry to connect every minute for ten minutes.
After ten minutes, it will retry once per hour instead. This is to avoid repeated lockup of other communication during failed connection tries.
H60 Publising topic structure
The data sent out from H60 is of format: <macaddress_of_h60>/HP/<index of sensor>
If only one H60 is connected to the MQTT server the wildcard + could be used instead of the mac address: +/HP/0001
Example format of topics published:
H60 Subsribing to topic
For H60 to receive data making changes in heat pump, it is listening to topics in the following format:
<mac address of H60>/HP/SET/<index>
So to set a value to 2204(example) use follwing topic:
cc50e12344ccdf/HP/SET/2204 with value of the setting
The CMD Topic
Additionally H60 is subscribing on the CMD topic to perform various actions.
Send data “STATUS” to the CMD topic to have H60 to publish current status. For example: Uptime, Wifi signal strength, etc.
Send data “GETALL” to the CMD topic to request H60 to publish an update on all heat pump data.
Example to request status, Send: “841d1t82daf0/HP/CMD” with data: “STATUS”
