emonHub Integration for Grant HP290 (EcoNet300)

[glyn.hudson]

Thanks to @dconlon it’s now possible to read data from Grant HP290 heat pump (econet300) locally via HTTP using just emonHub

After updating to master branch of emonHub, just add the following emonhub config to read data locally from Econet300:

[[Econet300HTTP]]
    Type = EmonHubEconet300Interfacer

    [[[init_settings]]]
        # Hostname or IP address of the ecoNET 300 bridge, if hostname doesnt work use local IP
        host = econet300.local
        # HTTP basic auth credentials for the ecoNET 300 bridge
        username = admin
        password = admin
        # Poll interval in seconds (time between successful polls)
        pollinterval = 60
    [[[runtimesettings]]]

There are multiple ways to read and control the Grant HP290, the various methods are documented on this thread:

Reading onboard data from Grant Aerona HP290 + Control

The Grant Aerona HP290 heat pump uses a Plum ecoMAX360i touch screen controller. It’s a good controller and works well. [image] The Grant HP290 must be the easiest heat pump to integrate with, no special cables or hardware is required, just local HTTP requests Grant use TP-Link hardware (EcoNet300) running custom firmware to post data to EcoNet24.com. EcoNet service allows every setting to be adjusted remotely and lots metrics from onboard sensors to be monitored with basic graphing…
