+### Comparing your device firmware with the current Tasmota GitHub Release
+
+Knowing your devices firmware version(s) is good.
+Being able to compare it with the current release directly, is even better.
+You can archive this by combining the maintenance actions with the openHAB http binding, the jsonpath transformation and the GitHub API.
+
+Just extend the maintenance setup with the following Item and config:
+
+**http.cfg:**
+```java
+# Tasmota Release Status (cached twice a day)
+tasmotaRelease.url=https://api.github.com/repos/arendst/Sonoff-Tasmota/tags
+tasmotaRelease.updateInterval=43200000
+```
+
+**sonoff.items:**
+```java
+String Sonoff_Current_FW_Available "Current Release [%s]" <sonoff_basic> (Sonoff_Maintenance) { http="<[tasmotaRelease:10000:JSONPATH($[0].name)]"}
+```
+
+With the item in your sitemap, you will now see the latest release/tag from the tasmota repository.
