Telegram notifier script for xiaomi temperature sensor

Setup, Configuration and Use Scripts & Rules
1

Hi!

I need a rule for my Xiaomi temperature and humidity sensor. I need to send notifications to my tg bot when the temperature is greater than 23 degrees. I try to use this:

rule "Xiaomi temp sensor"
when
    Channel "mihome:sensor_ht:xxxxxxxxxxxx:temperature" changed from 22.32 to 23.12
then
    sendTelegram("bot1", "Temp is changed")
end

but it’s not working ((

EDITED: And how to edit the script so that will sends notifications once an hour or only once ?

Thats because you use the channel.
Use the temperature item. And do it more “correctly” like this:

rule "Xiaomi temp sensor"
when
    Item [xiaomi temp sensor item] changed
then
   if ([xiaomi temp sensor item] > 23 )
    sendTelegram("bot1", "Temp is changed")
end

And, you should pay attention to the logfile as well. I would assume your rule would be triggering errors.

Thank for your support!
I change the script:

rule "Xiaomi temp sensor"
when
    Item [mihome:sensor_ht:xxxxxxxxxxxxxxx:temperature] changed
then
   if ([mihome:sensor_ht:xxxxxxxxxxxxxxxx:temperature] > 23 )
    sendTelegram("bot1", "Temp is changed")
end

but at the log file:

020-04-30 20:06:02.418 [WARN ] [el.core.internal.ModelRepositoryImpl] - Configuration model 'telegram.rules' has errors, therefore ignoring it: [3,5]: no viable alternative at input '['
[3,32]: mismatched character 'c' expecting set null

[5,16]: missing ')' at 'sensor_ht'
[5,25]: mismatched input ':' expecting 'end'
[5,30]: mismatched character 'c' expecting set null

Ahh, you need to remove the brackets [ ] I just inserted those so you could see where to put your item.

Like this:

rule "Xiaomi temp sensor"
when
    Item mihome:sensor_ht:xxxxxxxxxxxxxxx:temperature changed
then
   if (mihome:sensor_ht:xxxxxxxxxxxxxxxx:temperature > 23 )
    sendTelegram("bot1", "Temp is changed")
end
5 
cat /etc/openhab2/rules/telegram.rules
rule "Xiaomi temp sensor"
when
    Item mihome:sensor_ht:xxxxxxxxxxx:temperature changed
then
   if (mihome:sensor_ht:xxxxxxxxxxxxxxxx:temperature > 23 )
    sendTelegram("bot1", "Temp is changed")
end

stiil have a error:

2020-04-30 20:41:04.612 [WARN ] [el.core.internal.ModelRepositoryImpl] - Configuration model 'telegram.rules' has errors, therefore ignoring it: [3,5]: no viable alternative at input ':'

[5,14]: mismatched input ':' expecting ')'
[5,24]: mismatched input ':' expecting 'end'
[5,29]: mismatched character 'c' expecting set null

You previous post had a first linie which is NOT suppose to be in the rule file…
(This line: cat /etc/openhab2/rules/telegram.rules )

This is how you rule should look like:

rule "Xiaomi temp sensor"
when
    Item Xi_HT_Temperature changed
then
   if (Xi_HT_Temperature > 23 )
    sendTelegram("bot1", "Temp is changed")
end

And only this…
Please look closely how I inserted your item…

line cat /etc/openhab2/rules/telegram.rules is only linux command, it is not in the script.

changed on this:

rule "Xiaomi temp sensor"
when
    Item Xi_HT_Temperature changed
then
   if (Xi_HT_Temperature > 23 )
    sendTelegram("bot1", "Temp is changed")
end

now in log:
2020-05-01 00:15:09.769 [INFO ] [el.core.internal.ModelRepositoryImpl] - Loading model ‘telegram.rules’
2020-05-01 00:16:01.700 [ERROR] [ntime.internal.engine.RuleEngineImpl] - Rule ‘Xiaomi temp sensor’: Unknown variable or command ‘>’; line 5, column 8, length 22
2020-05-01 00:18:23.032 [ERROR] [ntime.internal.engine.RuleEngineImpl] - Rule ‘Xiaomi temp sensor’: Unknown variable or command ‘>’; line 5, column 8, length 22

You are looking to compare the Item’s state and I added a code block so that you could add more lines…

rule "Xiaomi temp sensor"
when
    Item Xi_HT_Temperature changed
then
    if (Xi_HT_Temperature.state > 23) {
        sendTelegram("bot1", "Temp is changed")
    }
end
11

The > < operators can be a bit funny in rules, you may need to try

if ((Xi_HT_Temperature.state as Number) > 23 )

12

Big thanks to all script now look like this:

rule "Xiaomi temp sensor"
when
    Item Xi_HT_Temperature changed
then
   if ((Xi_HT_Temperature.state as Number) > 23 )
    sendTelegram("bot1", "Temp is changed")
end

and in log only:

2020-05-01 00:36:20.698 [INFO ] [el.core.internal.ModelRepositoryImpl] - Refreshing model 'telegram.rules'

now it should work, I think.

13

And please tell me how to edit the script so that will sends notifications once an hour or only once ?

According to its doc… Like this:

I dont use the telegram action myself though, so I have no idea how it works. You probably have to set it up correctly. Read the doc. as linked.

You’d want the rule to trigger once an hour, instead of every time the temperature changes.
The magic word is cron trigger

But if the temperature changes to > 23, you might have to wait 59 minutes until the next time the rule runs. Can you say what you want in more detail?

For example -
Want a message as soon as temp > 23
But
Don’t want another message for one hour, and then I want a reminder if temp is still >23.
And
Want a reminder every hour as long as still > 23

16

Sorry for the inaccuracy. I want a reminder every half of hour as long as temperature is still > 23.

17

All the parts for that job will be in here -
