@mpp Guys in MySensors forum noticed I cleared EEPROM with zeros instead of 0xFF.

@jkandasa How could I wipe out database?

@jkandasa I upgraded a while ago when you fixed another DB error.
New error appeared with no particular reason.
Should I restore DB from backup?

I see the following errors in mycontroller.log and mycontroller process appears to be down:

I figured how to set dummy sensor by script called through REST API.

I created "Set DummySensor" groovy script:

def uid = "DummySensor"
def value = "1"
def sensor = mcApi.uidTag().getByUid(uid).getResource()
sensor.setValue(value)
mcApi.sensor().sendPayload(sensor);

and call it through the REST API:

curl "http://admin:admin@localhost:9880/mc/rest/scripts/runNow?bindings=%7B+%7D&script=operations%2FSet+DummySensor.groovy&scriptBindings=%7B%7D"

I defined rule that gets triggered when dummy sensor value changes.
No 5 sec delays anymore. Cool!

Looks like dummy sensor variable triggers rule much faster than repository variable.
How could I change sensor variable (referring by UID tag) through REST API?
Could you post sample HTTP payload?

@jkandasa Yes, followed https://easyengine.io/tutorials/linux/ubuntu-postfix-gmail-smtp/ and got it working in short time.

Any chance to overcome this limitation?
At least keep operations in the order they were added to the rule.

I guess local postfix server would address both issues (performance and email delivery reliability).

I defined rule that triggers execution of a few operations.
I'd like operations to be executed in a specific order.
When I add operations, they appear in the list in the alphabetical order.
Is there a way to reorder operations or add new item to the end of list?

• If rule executes series of operations, they are execute sequentially or in parallel?
• if one operation in the series is "Send email", is it executed asynchronously (and network and SMTP server don't affect timing of other operations in the series)?
• or "Send email" gets executed synchronously (e.g. controller delays execution of other operations in the series until Send Email succeeded)?
• if "Send Email" failed (for example, because of bad Internet connection), does controller retries to send email later? What's the retry interval? Does it retry indefinitely?
• Is it advisable to run local SMTP server to minimize impact on rule execution?

Thanks. Your fix helped

Do I need to repair database?

Is SQLite more reliable than default DB engine?
How would I migrate?

Here is a sample REST API call that modifies MyController repository variable:

curl -X PUT -H "Content-Type: application/json" -d '{"key":"Var1","value":"222"}' "http://demo:demo@demo.mycontroller.org/mc/rest/variables"

Looks like I could replace client that pushes data through REST API with a rule that uses condition script.
Condition script could read external file and return true/false accordingly.

How often MyController executes condition script (linked to the rule)? Every 5sec?

@jkandasa said:

@benya For now there is no doc for REST API. You have to refer source code.

Are there any samples?
I need to pass credentials and trigger some operation.

Besides REST API, MyController supports any other IPC?
May I trigger operation from external app or shell script on the same host?

@jkandasa said:

@benya Do you face any issue with out Synchronization?

I face potential issue in the following scenario:

• multiple PIRs tigger rule that reads/writes global variable and disables/enables timer
• timer reads global variable as well
• timer has counter=1 and self-disables when triggered

Therefore I need to synchronize access to the global variable and modifications of timer object.
Otherwise global variable and timer could be left in an unexpected state.

Where could I lookup REST API samples or docs?

Is any <String, Object> map accessible to Groovy scripts?
It would be possible to store there generic objects and use them for synchronization.

@jkandasa We need some mechanism to prevent race condition.
