If your Moocall HEAT system is not sending alerts, go through the checklist below:
1. Is the Collar Turned On?
The device should show a flashing blue light
No light = device is OFF
To turn the device on:
Press and hold the power button until the light turns on
Wait until you see the flashing blue light (this means it is active and connected)
Always check this before placing it on the bull
2. Has the Collar Been Charged?
After charging, the device automatically powers off
Must be manually turned back on
3. Is There Network Signal?
The collar uses mobile network
Poor signal = no alerts sent
4. Is the Bull in an Exclusion Zone?
Exclusion tags pause heat detection for ~1 hour
Used to avoid false alerts in yards or handling areas
5. Are All Cows Properly Tagged?
Every cow with the bull must have a Moocall RFID tag
The system depends on tag reads (up to ~2m range)
Tag should be linked to the correct cow in the app
To confirm the correct reading of the tags, please perform a tag test.
6. Is There Enough Bull Activity?
The system detects heat based on:
Time
Activity (movement/mounting)
Proximity (distance to tag)
If these thresholds are not met, no alert is triggered. If the bull is Lazy / inactive, lame, overworked (too many cows) or too young or inexperienced, he may not interact enough to trigger detections. Remember the recommended ratio is 1 bull per 50 cows.
7. Are There Too Many or Too Few Bulls?
Too many bulls → competition & false readings
Too few bulls → missed heats due to low coverage
Use one active bull at a time and rotate if needed.
8. Has the Bull Recently Joined the Herd?
Bulls need 3–5 days to settle
Early behaviour may be:
Overactive → false alerts
Underactive → missed heats
Always allow a settling period before relying on alerts.
9. Is Your Farm Setup Affecting Performance?
Outdoor = best performance
Indoor setups require:
Enough space (~5m² per cow)
Suitable layout (not narrow/slatted sheds)
10. Could There Be Tag or System Reading Issues?
In some cases:
Tags may be faulty and stop reading
Tags may be lost or broken
If multiple heats are missed, download a tag report as some tags may need replacing.
11. Could It Be a Technical Issue?
Less common, but possible:
Device not checking in
Internal fault (impact, water damage)
SIM/network issue
Important
Not receiving alerts does not usually mean the device is faulty
Most issues come from:
Tagging setup
Bull behaviour
Farm conditions
