OpenTherm attributes
From the Diagnostics download I some attributes that are not showing on the LTS Flow Temperature. Please see my diagnostics json for opentherm below to see and let me know if they are worth adding to the project.
"OpenTherm": { "chFlowActiveUpperSetpoint": 850, "chFlowActiveLowerSetpoint": 350, "dhwFlowSetpoint": 550, "dhwEnable": true, "featureActions": { "ModulationOnboarding": true }, "Enabled": true, "transmitter": { "messagesSentCount": 192403 }, "receiver": { "decodingErrorsCount": 1229 }, "operatingMode": "OTplus", "preDefinedRemoteBoilerParameters": { "dhwSetpointTransferEnable": true, "maxChSetpointTransferEnable": true, "dhwSetpointReadWrite": true, "maxChSetpointReadWrite": true, "dhwSetpointUpperBound": 600, "dhwSetpointLowerBound": 300, "dhwSetpoint": 600, "maxChSetpoint": 850, "maxChSetpointUpperBound": 850, "maxChSetpointLowerBound": 250 }, "ch1FlowSetpoint": 350, "ch1FlowEnable": false, "ch2FlowSetpoint": 350, "ch2FlowEnable": false, "operationalData": { "RelativeModulationLevel": 0, "MinimumModulationLevel": 0, "ChPressureBar": 14, "Ch1FlowTemperature": 400, "ChReturnTemperature": 380, "Dhw1Temperature": 270, "Dhw2Temperature": 0, "MaximumCapacityKw": 24, "BoilerExhaustTemperature": 11008, "SlaveStatus": 0 }, "roomTemperature": 168, "roomSetpoint": 150, "TrackedRoomId": 4 }, "Status": { "uptime": 92357, "freeHeap": 58584, "lowestFreeHeap": 19648, "lastResetReason": "WDT_RST", "taskUsageEnabled": false } } }
+1 for this, it would be useful to track the pressure to see if the system is leaking, and the flow and return to see how well the controller is putting opentherm to use. These are now surfaced in the official wiser app when running under opentherm:
How did you get to that diagnostics page? If it was possible it would be good if you could show the last error message from the boiler too.. it is funny you mention a leak I'm noticing my pressure falling off, not sure if it's a leak or PRV, but being able to see the pressure, or being able to calculate a delta periodically would help catch this... at least hopefully before someone in the house shouts that the shower is cold... 🫣
So if you look at the attributes on the flow temp sensor (on the hub device), you will see all these values. They have been there a long time. If you want to track some of them, you can use a template sensor. You can understand we dont show all these as sensors by default due to the number of them.
Got this to work on apex charts without creating a template
type: custom:apexcharts-card header: show: true title: Boiler Pressure show_states: true colorize_states: true graph_span: 24h span: start: day yaxis:
- min: 0 max: 3 apex_config: tickAmount: 6 series:
- entity: sensor.wiser_lts_boiler_flow_temperature attribute: ch_pressure_bar name: Pressure unit: bar stroke_width: 2 curve: smooth color: "#2196F3" show: legend_value: true
I used to get flow temperature on my HubR V1, but i've upgraded to a V2 and it doesn't seem to exist any more, and it doesn't show in the entity list, am I missing something?
Just on this the CH pressure has always been 1.4 do we know if the wiser app actually takes updates from opentherm or if 1.4 is the placeholder within the API?
