Home Assistant Statistics sensors

in SW and Settings

Hello, I have integrated the sensors and switches into my Home assistant setup. It is working fine now.

I have two questions:

Sensors doesn`t show up as statistic sensors when using the statistics card in HA. I believe there has to be added a valid state class line to the sensor configuration which Hydrosys is exporting to HA. See here: https://developers.home-assistant.io/docs/core/entity/sensor/#long-term-statistics
When I am restarting HA, the sensors/switches from hydrosys is losing connection, and I need to open Hydrosys and resend the configuration to HA. Is this a known problem?

Thank you for a great application, I have been using it in my greenhouse for three years now.

If possible I would prefer an auto update feature, to always keep it up to date.

Hello, where can I find these files?

For statistics, I also used InfluxDB and Grafana integration in HA. A bit of a learning curve but it works. You can also use the history-graph card which gives you a nice graph:

I also would have one request which would be to add a "force_update" but not certain if it should be done in Hydrosys or HA

force_update boolean (optional, default: false)

Sends update events even if the value hasn’t changed. Useful if you want to have meaningful value graphs in history.

I added the force_update in the HASScompMatrix.py and it does work well - now HA sensors are updated when a new mqtt payload comes in. Here's the mod i did for the "sensor" section only (line 486) :

payload={

"name":Name,

"device_class":sel_device_class,

"state_topic":state_topic,

"unit_of_measurement":unit_of_measurement,

"force_update": True

"value_template":"{{value_json['"+Name+"']}}",

"unique_id": device_name + "-" + Name

#"device":{"name":device_name,"model":"aa","manufacturer":"daje","identifiers":["hydrosys4"]}

}

Here's a screenshot from HA payload showing the force_update: true

Here's the info from HA:

In an ideal scenario, the MQTT device will have a state_topic to publish state changes. If these messages are published with a RETAIN flag, the MQTT switch will receive an instant state update after subscription, and will start with the correct state. Otherwise, the initial state of the switch will be unknown. A MQTT device can reset the current state to unknown using a None payload.

Hello,

Thanks for the feedback,

for the point 1) I was not aware of it, when I have time I'll have a look at it.

point 2) I notice the issue when I got a power outage. After some research I understood that the setting made using mqtt are a sort of volatile, so they cannot be stored permanently. Have to say this is quite disappointing, so far I have not found a way to solve the issue.

Did you test the changes? When I look at the file the items I had updated are not changed:

File: HASSintegrMQTT.py (directory home/pi/env/autonom)

I modified the HASSintegrMQTT.py in 2 places (line 325 and 329)

where i changed the "retained=False" to "retained=True".

So far it has worked. will keep on monitoring.

I did a few rebooting of HomeAssistant and it is working fine,

HomeAssistant gets the "retained values" from Hydrosys4. So if you need

to resolve this issue make the modification i mentionned above.

Line 325:

def publish(self, topic, payload, qos=0, retained=True, properties=None): # change from False to True

self.clientobj.publish(topic, payload, qos, retained)

Line 329:

def publish_wait_QoS2(self, topic, payload, retained=True, properties=None): #change from False to True

infot=self.clientobj.publish(topic, payload, qos=2)

infot.wait_for_publish()

(rc, mid)=infot

print(self.clientid + " " + "Topic: " + topic + " Payload " + payload)

-----------------------------------------------------------------------------------------------------------------------

File: HASScompMatrix.py (directory home/pi/env/autonom)

I added the "force_update": True in the HASScompMatrix.py and it does work well -

now HA sensors are updated when a new mqtt payload comes in. Here's the

mod i did for the "sensor" section only (line 486 - add after line 490) :

Line 486:

payload={

"name":Name,

"device_class":sel_device_class,

"state_topic":state_topic,

"unit_of_measurement":unit_of_measurement,

"force_update": True

"value_template":"{{value_json['"+Name+"']}}",

"unique_id": device_name + "-" + Name

#"device":{"name":device_name,"model":"aa","manufacturer":"daje","identifiers":["hydrosys4"]}

}

return payload
