This sensor allows you to calculate the average state for one or more sensors over a specified period. It pings the pack voltage via MQTT when charging to HA. May 21, 2022 · I have a sensor have 3 states (ON, Off, ON-LPI) I am trying to set up a history states sensor to calculate how much time the sensor is in (ON-LPI) state before changing to other states, In other words, time reset and r… Apr 7, 2022 · Hi all! I have a DIY electric motorbike, which runs a custom BMS system. I’ve got ecoflow powerstream and octopus energy supplier. However, I still want a third sensor . The meter works with two Min/Max The Min/Max integration consumes the state from other sensors to determine the minimum, maximum, latest (last), mean, median, range and sum of the collected states. We would like to show you a description here but the site won’t allow us. loja_ecuador 4 days ago · I placed x3 Shelly EM to measure the current flowing, and in Home assistant I have the 3x power values on each line. daily_yield and sensor. A lot of issues I could find on the forum, but there is one thing I couldn’t figure out. The integration sensors are updated whenever the source changes and, optionally, based on a predefined time interval. They allow you to apply logic, perform calculations, extract specific pieces of information, and combine data points using the powerful Jinja2 templating engine built into Home Assistant. yaml, but it's not really practical for large number of sensors with many different calculated outputs or when you just need to perform a quick calculation on a certain sensor. cozify_han_power_total sensor created by the integration to calculate the electricity price in real time. 100% is 116. Sensor C = sensor A - sensor B. For de May 7, 2025 · The problem The AccuWeather integration is producing a KeyError: 5 when trying to process pollen category data for the forecast day sensors (e. May 1, 2019 · I’ve set up Home Assistant to receive SNMP data from Windows File Server in the form of sensors. Calculations without templates Another noob question :) I know I can convert or calculate sensor values with templates in sensors. Why Use Template Sensors? Data Transformation: Convert units, perform mathematical operations, or clean up messy data. Jan 23, 2026 · This page provides a technical overview of the sensor entities created by the SMA Speedwire integration and the mechanisms used to retrieve, process, and expose inverter data to Home Assistant. If you are like me, you want to self host literally everything. Advanced template sensors represent the pinnacle of Home Assistant's sensor capabilities, enabling sophisticated data processing, complex calculations, and intelligent decision-making through powerful Jinja2 templating. The SNMP data is in the form of OIDs and I can get total disk space and used disk space. I got the readings working from the meter which is really nice. Initially it was written special for calculating of average temperature, but now it can calculate Instructions on how to integrate Derivative Sensor into Home Assistant. The sensor config is as follows platform: mqtt name: ‘3Fazer - Voltage’ state_topic: ‘ev/3fazer’ unit_of_measurement: 'V I would like to convert this voltage to battery charge % if possible inside HA.
