Hi All,
I am relative new to H.A, using it for some months now, and slowly enhancing my install.
At this moment I would like to send a message via telegram when my P1 readings have increasing values for either low, or high tariff power returning to the grid (in other words, I should be doing something more useful with this energy: charging car, heating water etc…)
I created two sensors for this purpose, with this in the configuration file:
binary_sensor:
- platform: trend
sensors:
trend_ret_low:
entity_id: sensor.ret_low
#sample_duration: 180
#max_samples: 3
#min_gradient: -0.0008
device_class: power
trend_ret_high:
entity_id: sensor.ret_high
#sample_duration: 180
#max_samples: 3
#min_gradient: 0.0008
device_class: power
and an automation:
- id: '1000000000001'
alias: return_high
trigger:
- platform: numeric_state
entity_id: sensor.ret_high
above: '5'
action:
- service: telegram_bot.send_message
data:
message: <I>return high!</I>
title: <b>Home Assistant:</b>
parse_mode: html
- id: '1652598475510'
alias: return_low
description: ''
trigger:
- platform: numeric_state
entity_id: sensor.ret_low
above: '5'
condition: []
action:
- service: telegram_bot.send_message
data:
message: <I>return low!</I>
title: <b>Home Assistant:</b>
parse_mode: html
mode: single
If I check the statistics for both the ‘ret_low’ or ‘ret_high’ sensors, they show a increment:
However, the messages are send at really strange times (in the night), which is a but strange when there is no sun 
Any tips are welcome for improvements on either my config, and my knowledge of how this should be interpreted…
